Paleontologists find insufficient evidence that iconic Tyrannosaurus rex should be reclassified
About 201 million years ago, volcanic eruptions covered an area roughly the size of South America in lava as Pangaea started to split. The Earth was changed. In the years that followed, 40% of all four-legged land animals were wiped out in the End Triassic Extinction (ETE). The exact cause was unknown. However, researchers recently discovered that atmospheric changes as a result of the eruptions caused freezing temperatures at high latitudes. The land animals that survived had feathers or hair as insulation: large dinosaurs.
ROM (Royal Ontario Museum) revealed new research based on a cache of fossils that contains the brain and nervous system of a half-billion-year-old marine predator from the Burgess Shale called Stanleycaris
An international team that includes a University of Minnesota Twin Cities researcher has discovered a new big, meat-eating dinosaur, dubbed Meraxes gigas, that provides clues about the evolution and anatomy of predatory dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex.
Millions of years ago, giant dwarf crocodiles roamed a part of Africa with a taste for our human ancestors.
For decades, paleontologists have debated whether dinosaurs were warm-blooded, like modern mammals and birds, or cold-blooded, like modern reptiles.
A group of paleontologists, included researchers from the Ural Federal University (UrFU), discovered the jaws of an Etruscan bear from the early Pleistocene period (2–1.5 million years ago) in the Taurida cave.

Did the world’s largest prehistoric shark need an orthodontist, or did it just have a bad lunch?
Researchers have developed formulas that can calculate the body size of a primate based on the root size of its teeth. The formulas could allow researchers to make use of partial and incomplete fossils in order to learn how ancient primates – including human ancestors – interacted with their environment.
Fossil footprints found in an Australian coal mine around 50 years ago have long been thought to be that of a large ‘raptor-like’ predatory dinosaur, but scientists have in fact discovered they were instead left by a timid long-necked herbivore.
A team of paleontologists from the University of Washington excavated four dinosaurs in northeastern Montana this summer. The four dinosaur fossils are: the ilium of an ostrich-sized theropod; the hips and legs of a duck-billed dinosaur; a pelvis and limbs from another theropod; and a Triceratops specimen.
Researchers from the Universities of Tübingen and Zaragoza have discovered a previously unknown species of otter from 11.4-million-year-old strata at the Hammerschmiede fossil site.
In a paper published August 23, authors Cameron Pahl and Luis Ruedas, of Portland State University, show that Allosaurus, a large carnivorous dinosaur from the Jurassic that has long been thought to be a top predator, could probably have acquired most of its calories by scavenging on the carcasses of enormous sauropod herbivores that lived alongside it.
Tyrannosaurus rex was not just a huge beast with a big bite, it had nerve sensors in the very tips of its jaw enabling it to better detect – and eat – its prey, a new study published in the peer-reviewed journal Historical Biology today finds.
Research published today in the peer-reviewed Journal of Systematic Palaeontology describes the discovery of three new species of ancient creatures from the dawn of modern mammals, and hints at rapid evolution immediately after the mass extinction of the dinosaurs.
Newly-hatched pterosaurs may have been able to fly but their flying abilities may have been different from adult pterosaurs, according to a study published in Scientific Reports . Pterosaurs were a group of flying reptiles that lived during the Triassic,…
When it was discovered in the 1980s in Argentina, this hadrosaur was diagnosed with a fractured foot. However, a new analysis now shows that this ornithopod commonly known as the duck-billed dinosaur actually had a tumour some 70 million years…
GAINESVILLE, Fla. — Two fossil teeth from a distant relative of North American gophers have scientists rethinking how some mammals reached the Caribbean Islands. The teeth, excavated in northwest Puerto Rico, belong to a previously unknown rodent genus and species,…
Professors in Syracuse University’s College of Arts and Sciences explored whether or not the scientific community will ever be able to settle on a ‘total number’ of species of living vertebrates, which could help with species preservation. By knowing what’s…
The average body size of humans has fluctuated significantly over the last million years and is strongly linked to temperature. Colder, harsher climates drove the evolution of larger body sizes, while warmer climates led to smaller bodies. Brain size also…
Discovery illuminates a 120-million-year record of ancient Earth
A new paper appearing in Biology Letters describes the oldest-known fragmentary bat fossils from Asia, pushing back the evolutionary record for bats on that continent to the dawn of the Eocene and boosting the possibility that the bat family’s “mysterious” origins someday might be traced to Asia.
LAWRENCE — A new paper appearing in Biology Letters describes the oldest-known fragmentary bat fossils from Asia, pushing back the evolutionary record for bats on that continent to the dawn of the Eocene and boosting the possibility that the bat…
Professor Beverly Saylor leads interdisciplinary global group applying state-of-the art technology to answer ancient questions
Paleontologists from Univeristy of Liège (Belgium) redefine the geological boundary between the Devonian and Carboniferous periods. A Walloon site could be chosen as a world reference for this boundary.
Using an exceptionally preserved fossil from South Africa, a particle accelerator, and high-powered x-rays, an international team including a University of Minnesota researcher has discovered that not all dinosaurs breathed in the same way. The findings give scientists more insight…
Researchers at the UPV/EHU-University of the Basque Country describe two palaeotheriidae mammals that lived in the subtropical landscape of Alava
The results indicate that shark abundance in the region declined roughly three-fold since prehistoric times
The tiny beetle Triamyxa coprolithica is the first-ever insect to be described from fossil faeces. The animal the researchers have to thank for the excellent preservation was probably the dinosaur ancestor Silesaurus opolensis, which 230 million years ago ingested the small beetle in large numbers.
Based on fossil finds, we know that the vast majority of species that once inhabited the earth have become extinct. For example, there are about 5,500 mammal species living on the planet today, but we know of at least 160,000…
Elephants and their forebears were pushed into wipeout by waves of extreme global environmental change, rather than overhunting by early humans, according to new research. The study, published today in Nature Ecology & Evolution , challenges claims that early human…
Dinosaurs roamed the Earth more than 65 million years ago, and paleontologists and amateur fossil hunters are still unearthing traces of them today. The minerals in fossilized eggs and shell fragments provide snapshots into these creatures’ early lives, as well…
Ten million years before the well-known asteroid impact that marked the end of the Mesozoic Era, dinosaurs were already in decline. That is the conclusion of the Franco-Anglo-Canadian team led by CNRS researcher Fabien Condamine from the Institute of Evolutionary…
