Europe's very own dinosaurs -- the enigmatic Late Cretaceous rhabdodontids //www.koonmotors.com/releases/2023/08/230830131713.htm A new study brings together intriguing details about the little-known Rhabdodontidae dinosaurs of Late Cretaceous Europe. These gregarious herbivores, characterized by robust builds and beaks specialized for tough vegetation, inhabited the European archipelago. Despite being widespread and abundant, they vanished in Western Europe due to environmental changes around 69 million years ago, while surviving longer in Eastern Europe. Their fossil record offers valuable insights into their evolution and lifestyle, although its limited nature still challenges comprehensive understanding. Wed, 30 Aug 2023 13:17:13 EDT //www.koonmotors.com/releases/2023/08/230830131713.htm Newly discovered 'primitive cousins of T rex' shed light on the end of the age of dinosaurs in Africa //www.koonmotors.com/releases/2023/08/230823122557.htm Researchers have discovered the fossils of two new abelisaurs in Morocco, showing the diversity of dinosaurs in this region at the end of the Cretaceous period. Wed, 23 Aug 2023 12:25:57 EDT //www.koonmotors.com/releases/2023/08/230823122557.htm Scientists explore dinosaur 'Coliseum' in Denali National Park //www.koonmotors.com/releases/2023/08/230814174542.htm Scientists have discovered and documented the largest known single dinosaur track site in Alaska. The site, located in Denali National Park and Preserve, has been dubbed 'The Coliseum' by researchers. Mon, 14 Aug 2023 17:45:42 EDT //www.koonmotors.com/releases/2023/08/230814174542.htm New archosaur species shows that precursor of dinosaurs and pterosaurs was armored //www.koonmotors.com/releases/2023/07/230726113005.htm 研究人员描述了一种新的armored reptile that lived near the time of the first appearance of dinosaurs. With bony plates on its backbone, this archosaur fossil reveals that armor was a boomerang trait in the story of dinosaur and pterosaur evolution: the group's ancestors were armored, but this characteristic was lost and then independently re-evolved multiple times later among specialized dinosaurs like ankylosaurs, stegosaurs, and others. Wed, 26 Jul 2023 11:30:05 EDT //www.koonmotors.com/releases/2023/07/230726113005.htm Unusual fossil shows rare evidence of a mammal attacking a dinosaur //www.koonmotors.com/releases/2023/07/230718164250.htm Scientists have described an unusual fossil from around 125 million years ago in China that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur. The two animals are locked in mortal combat, and it's among the first evidence to show actual predatory behavior by a mammal on a dinosaur. The fossil's presence challenges the view that dinosaurs had few threats from their mammal contemporaries during the Cretaceous, when dinosaurs were the dominant animals. Tue, 18 Jul 2023 16:42:50 EDT //www.koonmotors.com/releases/2023/07/230718164250.htm Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died //www.koonmotors.com/releases/2023/07/230705154016.htm Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers. Wed, 05 Jul 2023 15:40:16 EDT //www.koonmotors.com/releases/2023/07/230705154016.htm Newly discovered Jurassic fossils in Texas //www.koonmotors.com/releases/2023/06/230627191544.htm Scientists have filled a major gap in the state's fossil record -- describing the first known Jurassic vertebrate fossils in Texas. The weathered bone fragments are from the limbs and backbone of a plesiosaur, an extinct marine reptile. Tue, 27 Jun 2023 19:15:44 EDT //www.koonmotors.com/releases/2023/06/230627191544.htm Humans' ancestors survived the asteroid impact that killed the dinosaurs //www.koonmotors.com/releases/2023/06/230627123015.htm A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct. Tue, 27 Jun 2023 12:30:15 EDT //www.koonmotors.com/releases/2023/06/230627123015.htm New dinosaur discovered: Ankylosaurs may have been far more diverse than originally thought //www.koonmotors.com/releases/2023/06/230616161945.htm First armoured dinosaur to be described from the Isle of Wight in 142 years, shows Ankylosaurs may have been far more diverse than originally thought Fri, 16 Jun 2023 16:19:45 EDT //www.koonmotors.com/releases/2023/06/230616161945.htm First side-necked turtle ever discovered in UK //www.koonmotors.com/releases/2023/06/230613190825.htm The first side-necked turtle ever to be found in the UK has been discovered by an amateur fossil collector and palaeontologists. Tue, 13 Jun 2023 19:08:25 EDT //www.koonmotors.com/releases/2023/06/230613190825.htm Ancient herbivore's diet weakened teeth leading to eventual starvation, study suggests //www.koonmotors.com/releases/2023/06/230609125712.htm Researchers have shed light on the life of the ancient reptile Rhynchosaur, which walked the earth between 250-225 million years ago, before being replaced by the dinosaurs. Fri, 09 Jun 2023 12:57:12 EDT //www.koonmotors.com/releases/2023/06/230609125712.htm New dino, 'Iani,' was face of a changing planet //www.koonmotors.com/releases/2023/06/230607215807.htm A newly discovered plant-eating dinosaur may have been a species' 'last gasp' during a period when Earth's warming climate forced massive changes to global dinosaur populations. Wed, 07 Jun 2023 21:58:07 EDT //www.koonmotors.com/releases/2023/06/230607215807.htm Multiple species of semi-aquatic dinosaur may have roamed pre-historic Britain //www.koonmotors.com/releases/2023/06/230601160144.htm Palaeontologists studying a British dinosaur tooth have concluded that several distinct groups of spinosaurs -- dinosaurs with fearsome crocodile-like skulls -- inhabited southern England over 100 million years ago. Thu, 01 Jun 2023 16:01:44 EDT //www.koonmotors.com/releases/2023/06/230601160144.htm 107-million-year-old pterosaur bones: Oldest in Australia //www.koonmotors.com/releases/2023/05/230530124840.htm A team of researchers have confirmed that 107-million-year-old pterosaur bones discovered more than 30 years ago are the oldest of their kind ever found in Australia, providing a rare glimpse into the life of these powerful, flying reptiles that lived among the dinosaurs. Tue, 30 May 2023 12:48:40 EDT //www.koonmotors.com/releases/2023/05/230530124840.htm Dinosaurs were the first to take the perspectives of others //www.koonmotors.com/releases/2023/05/230522131341.htm Understanding that others hold different viewpoints from your own is essential for human sociality. Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings challenge the idea that mammals were the originators of novel and superior forms of intelligence in the wake of the dinosaur extinction. Mon, 22 May 2023 13:13:41 EDT //www.koonmotors.com/releases/2023/05/230522131341.htm Fossil of mosasaur with bizarre 'screwdriver teeth' found in Morocco //www.koonmotors.com/releases/2023/05/230518120907.htm Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent finds from Africa, it suggests that mosasaurs and other marine reptiles were evolving rapidly up until 66 million years ago, when they were wiped out by an asteroid along with the dinosaurs and around 90% of all species on Earth. Thu, 18 May 2023 12:09:07 EDT //www.koonmotors.com/releases/2023/05/230518120907.htm Giants of the Jurassic seas were twice the size of a killer whale //www.koonmotors.com/releases/2023/05/230510120558.htm There have been heated debates over the size of Jurassic animals. The speculation was set to continue, but now a chance discovery in an Oxfordshire museum has led to palaeontologists publishing a paper on a Jurassic species potentially reaching a whopping 14.4 meters -- twice the size of a killer whale. Wed, 10 May 2023 12:05:58 EDT //www.koonmotors.com/releases/2023/05/230510120558.htm Analysis of dinosaur eggshells: Bird-like Troodon laid 4 to 6 eggs in a communal nest //www.koonmotors.com/releases/2023/04/230403162635.htm An international research team has determined that Troodon, a dinosaur very close to modern birds, was a warm-blooded animal (an endotherm), but had a reproductive system similar to that of modern reptiles. The scientists applied a new method which allowed for accurate determination of the temperature when the egg's carbonate shell was formed. Furthermore, the researchers showed that Troodon laid 4 to 6 eggs per clutch. As nests with up to 24 Troodon eggs had been found, the scientists conclude that several Troodon females laid their eggs in communal nests. Mon, 03 Apr 2023 16:26:35 EDT //www.koonmotors.com/releases/2023/04/230403162635.htm Predatory dinosaurs such as T. rex sported lizard-like lips //www.koonmotors.com/releases/2023/03/230330172120.htm A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths. Thu, 30 Mar 2023 17:21:20 EDT //www.koonmotors.com/releases/2023/03/230330172120.htm Dinosaur claws used for digging and display //www.koonmotors.com/releases/2023/02/230227132633.htm Dinosaur claws had many functions, but now a team has shown some predatory dinosaurs used their claws for digging or even for display. 2023年2月27日,星期一,13:26:33 EST //www.koonmotors.com/releases/2023/02/230227132633.htm Evolution of dinosaur body size through different developmental mechanisms //www.koonmotors.com/releases/2023/02/230223181827.htm 食肉恐龙被称为食肉恐龙roamed the ancient Earth ranged in size from the bus-sized T. rex to the smaller, dog-sized Velociraptor. Scientists puzzling over how such wildly different dinosaur sizes evolved recently found -- to their surprise -- that smaller and larger theropod dinosaurs like these didn't necessarily get that way merely by growing slower or faster. Thu, 23 Feb 2023 18:18:27 EST //www.koonmotors.com/releases/2023/02/230223181827.htm Oldest spinosaur brains revealed //www.koonmotors.com/releases/2023/02/230213201105.htm Researchers have reconstructed the brains and inner ears of two British spinosaurs, helping uncover how these large predatory dinosaurs interacted with their environment. Mon, 13 Feb 2023 20:11:05 EST //www.koonmotors.com/releases/2023/02/230213201105.htm Researchers uncover 92 fossil nests belonging to some of India's largest dinosaurs //www.koonmotors.com/releases/2023/01/230118195852.htm The discovery of more than 250 fossilized eggs reveals intimate details about the lives of titanosaurs in the Indian subcontinent, according to a new study. Wed, 18 Jan 2023 19:58:52 EST //www.koonmotors.com/releases/2023/01/230118195852.htm Fossils reveal dinosaurs of prehistoric Patagonia //www.koonmotors.com/releases/2023/01/230112155821.htm A study is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of theropods -- a dinosaur group that includes both modern birds and their closest non-avian dinosaur relatives -- from the Chilean portion of Patagonia. The researchers' finds include giant megaraptors with large sickle-like claws and birds similar to todays ducks and geese. Thu, 12 Jan 2023 15:58:21 EST //www.koonmotors.com/releases/2023/01/230112155821.htm The other paleo diet: Rare discovery of dinosaur remains preserved with its last meal //www.koonmotors.com/releases/2022/12/221221121310.htm Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs. Wed, 21 Dec 2022 12:13:10 EST //www.koonmotors.com/releases/2022/12/221221121310.htm What the inner ear of Europasaurus reveals about its life //www.koonmotors.com/releases/2022/12/221220112430.htm Europasaurus is a long-necked, herbivorous dinosaur that lived in the Late Jurassic, about 154 million years ago, on a small island in modern-day Germany. Recently, scientists examined fossil braincase material of Europasaurus with the aid of micro-computed tomography (micro-CT). The digital reconstruction of the inner ear of Europasaurus gave the researchers new insights not only into its hearing ability, but also into its reproductive and social behavior. Tue, 20 Dec 2022 11:24:30 EST //www.koonmotors.com/releases/2022/12/221220112430.htm Scientists discover what was on the menu of the first dinosaurs //www.koonmotors.com/releases/2022/12/221216142623.htm The earliest dinosaurs included carnivorous, omnivorous and herbivorous species, according to a team of palaeobiologists. Fri, 16 Dec 2022 14:26:23 EST //www.koonmotors.com/releases/2022/12/221216142623.htm Climate change played key role in dinosaur success story //www.koonmotors.com/releases/2022/12/221216112905.htm Climate change, rather than competition, played a key role in the ascendancy of dinosaurs through the Late Triassic and Early Jurassic periods. Fri, 16 Dec 2022 11:29:05 EST //www.koonmotors.com/releases/2022/12/221216112905.htm Dinosaur teeth reveal what they didn't eat //www.koonmotors.com/releases/2022/12/221209094728.htm Scratches on dinosaur teeth could reveal what they really ate. Dental microwear texture analysis (DMTA) has now been used to infer the feeding habits of large theropods, including Allosaurus and T. rex. By taking 3D images of individual teeth and analyzing the pattern of marks scratched into them, researchers could reason which dinosaurs may have frequently crunched on hard bone and which may have regularly eaten softer foods and prey. This technique opens up a new avenue of research for paleontology, helping us to better understand not only dinosaurs themselves but also the environment and communities in which they lived. Fri, 09 Dec 2022 09:47:28 EST //www.koonmotors.com/releases/2022/12/221209094728.htm Dinosaurs were on the up before asteroid downfall //www.koonmotors.com/releases/2022/12/221207142210.htm Dinosaurs dominated the world right up until a deadly asteroid hit the earth, leading to their mass extinction, some 66 million years ago, a landmark study reveals. Fresh insights into dinosaurs' ecosystems -- the habitats and food types that supported their lives -- suggests that their environments were robust and thriving, right up until that fateful day, at the end of the Cretaceous period. Wed, 07 Dec 2022 14:22:10 EST //www.koonmotors.com/releases/2022/12/221207142210.htm Ankylosaurs battled each other as much as they fought off T. rex //www.koonmotors.com/releases/2022/12/221206204908.htm Scientists have found new evidence for how armored dinosaurs used their iconic tail clubs. The exceptional fossil of the ankylosaur Zuul crurivastator has spikes along its flanks that were broken and re-healed while the dinosaur was alive -- injuries that the scientists think were caused from a strike by another Zuul's massive tail club. This suggests ankylosaurs had complex behavior, possibly battling for social and territorial dominance or even engaging in a 'rutting' season for mates. Tue, 06 Dec 2022 20:49:08 EST //www.koonmotors.com/releases/2022/12/221206204908.htm Fossil overturns more than a century of knowledge about the origin of modern birds //www.koonmotors.com/releases/2022/11/221130114507.htm Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds. Wed, 30 Nov 2022 11:45:07 EST //www.koonmotors.com/releases/2022/11/221130114507.htm Oldest Pterodactylus fossil found in Germany //www.koonmotors.com/releases/2022/11/221129112745.htm The oldest Pterodactylus specimen was found near Painten, Germany. The fossil is about one million years older than other Pterodactylus specimens. The specimen is a complete, well-preserved skeleton of a small-sized individual. With a 5-cm-long skull, it represents a rare 'sub-adult' individual. Tue, 29 Nov 2022 11:27:45 EST //www.koonmotors.com/releases/2022/11/221129112745.htm Prehistoric predator? Artificial intelligence says no //www.koonmotors.com/releases/2022/11/221115113742.htm Artificial intelligence has revealed that prehistoric footprints thought to be made by a vicious dinosaur predator were in fact from a timid herbivore. Tue, 15 Nov 2022 11:37:42 EST //www.koonmotors.com/releases/2022/11/221115113742.htm New Scottish fossil sheds light on the origins of lizards //www.koonmotors.com/releases/2022/10/221026114346.htm A fossil discovery from Scotland has provided new information on the early evolution of lizards, during the time of the dinosaurs. Wed, 26 Oct 2022 11:43:46 EDT //www.koonmotors.com/releases/2022/10/221026114346.htm Fossil bird's skull reconstruction reveals a brain made for smelling and eyes made for daylight //www.koonmotors.com/releases/2022/10/221024153616.htm πecing together the crushed skull of a fossil bird that lived alongside the dinosaurs helped researchers extrapolate what its brain would have looked like: big olfactory bulbs would have meant that this bird, the earliest known animal to eat fruit, had a better sense of smell than most modern birds. And the bones around its eye sockets revealed that it would have been better at seeing by day than at night.

Thu, 22 Sep 2022 10:31:47 EDT //www.koonmotors.com/releases/2022/09/220922103147.htm Discovery of extinct prehistoric reptile that lived among dinosaurs //www.koonmotors.com/releases/2022/09/220915123701.htm 研究人员已经发现了一种新的物种灭绝of lizard-like reptile that belongs to the same ancient lineage as New Zealand's living tuatara. A team of scientists describe the new species Opisthiamimus gregori, which once inhabited Jurassic North America about 150 million years ago alongside dinosaurs like Stegosaurus and Allosaurus. In life, this prehistoric reptile would have been about 16 centimeters (about 6 inches) from nose to tail -- and would fit curled up in the palm of an adult human hand -- and likely survived on a diet of insects and other invertebrates. Thu, 15 Sep 2022 12:37:01 EDT //www.koonmotors.com/releases/2022/09/220915123701.htm What killed dinosaurs and other life on Earth? //www.koonmotors.com/releases/2022/09/220912152923.htm Determining what killed the dinosaurs 66 million years ago at the end of the Cretaceous Period has long been the topic of debate, as scientists set out to determine what caused the five mass extinction events that reshaped life on planet Earth in a geological instant. Some scientists argue that comets or asteroids that crashed into Earth were the most likely agents of mass destruction, while others argue that large volcanic eruptions were the cause. A new study reports that volcanic activity appears to have been the key driver of mass extinctions.

Tue, 03 May 2022 09:17:54 EDT //www.koonmotors.com/releases/2022/05/220503091754.htm Precipitation helped drive distribution of Alaska dinosaurs //www.koonmotors.com/releases/2022/05/220502170938.htm Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research. The finding discusses the distribution of hadrosaurids and ceratopsids -- the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago.

Wed, 06 Apr 2022 16:05:29 EDT //www.koonmotors.com/releases/2022/04/220406160529.htm T. rex's short arms may have lowered risk of bites during feeding frenzies //www.koonmotors.com/releases/2022/04/220401094852.htm Extinct for 66 million years, T. rex still inspires speculation about its anatomy, behavior and fierce physique. One conundrum: its peculiarly short forelimbs, which have relatively limited mobility. While scientists have suggested explanations, a paleontologist puts the proposals to the test and finds them wanting. He hypothesizes that the arms reduced in size to limit damage, possibly fatal, when a pack of T. rexes descended on a carcass with their bone-crunching teeth.

In a new paper, palaeontologists have taken a different approach to decipher the lifestyle of long-extinct creatures: examining the density of their bones.
