New reptile species discovered with 250 million year old fossil

New reptile species discovered with 250 million year old fossil

A team of scientists have discovered a fossilized reptile skull dating back 250 million years, revealing not only evidence of a new species, but connections to the origins of dinosaurs as well. The skull, found by paleontologists from universities in Brazil and the UK, is well-preserved and features a number of serrated teeth, and is said to have survived a mass extinction event that occurred roughly 252 million years ago, eradicating 90% of life on Earth.

Study finds that dinosaurs may have evolved much faster than previously thought

Study finds that dinosaurs may have evolved much faster than previously thought

To understand our world and its future, we often must look to the past. Clues about the evolution of the planet and its inhabitants are scattered in the ground, which helps unlock the mysteries about the past. Unfortunately, sometimes deciphering those clues can be difficult, and the smallest error in calculations can put the dates of events off by millions of years, as one group of researchers recently found.

Newly discovered dinosaur footprints reveal they once roamed Scottish lagoon

Newly discovered dinosaur footprints reveal they once roamed Scottish lagoon

Researchers recently uncovered Scotland's largest dinosaur site when they came across hundreds of dinosaur footprints dating as far back as 170 million years. The site was found near the Isle of Skye, along the nation's shore, with data indicating the footprints were left in the Middle Jurassic period, when the area was a sandy, saltwater lagoon. Not only do scientists know what kind of dinosaur left the footprints, but that they were likely walking in shallow water when the prints were made.

South Dakota was once home to giant raptors

South Dakota was once home to giant raptors

The fossilized remains of one of the largest raptors ever have been discovered in South Dakota. The discovery was made by Palm Beach Museum curator of vertebrate paleontology Robert DePalma and a team in Harding County at Hell Creek Formation. The fossils are of a partial skeleton belonging to the giant raptor dubbed “Dakotaraptor steini”, a member of the dromaeosauridae family.

T-Rex study shows how terrifying dinosaurs’ jaw truly was

T-Rex study shows how terrifying dinosaurs’ jaw truly was

A study on the Tyrannosaurus rex, one of the most widely-known and loved dinosaurs in our short history, shows that this beast had a magnificent set of chompers. T-rex is shown by paleontologist Dr Stephan Lautenschlager to possess a sustained muscle force for a wide range of jaw angles. T-rex and a couple of other theropod dinosaurs were studied, showing the maximal jaw gape of the beloved thunder-lizard's jaw to be a whopping 63.5-inches. And that's not even the widest a theropod's jaw got.

Dinosaur eggs change perceptions of blood connections to birds

Dinosaur eggs change perceptions of blood connections to birds

A new study on dinosaur eggs sheds light on a 150-year-old debate over the warm- or cold-bloodedness of the thunder lizard. Late Cretaceous titanosaurid eggshells were studied and contrasted with oviraptorid eggshells, both of which yield clumped isotopes that allowed scientists to compare thermophysiology of these extinct species to their modern-day counterparts. With these studies, determinations can be made on the body temperatures of females during periods of ovulation. Body temperatures of these species indicate that, as the study suggests, "not all dinosaurs had body temperatures in the range of that seen in modern birds", dousing previous suspicions of the opposite.

This massive furry rodent outlived the dinosaurs

This massive furry rodent outlived the dinosaurs

Scientists discover ancient furry creature that outlived the dinosaurs asteroid-and-volcano induced extinction. Just when you think whatever killed the dinosaurs must have been a total live-destroying extinction level event, a tiny rodent arrives. This beaver-like creature was discovered by scientists in northwestern New Mexico's badlands. Its name is Kimbetopsalis simmonsae, and the example found in New Mexico was around 3-feet long (right around 1-meter). This creature did end up going extinct itself in the late Palaeocene, but before then it went on to reach weights up to 100kg - 220 pounds!

Mammoth bones found by farmer in Michigan

Mammoth bones found by farmer in Michigan

This week the bones of a wholly mammoth have been found in a field by a farmer in Michigan. The bones are said to have been found when farmer James Bristle and a friend were digging to place drainage tiles. Once Bristle realized what they'd hit wasn't an old fence post, and instead a bone from an animal he didn't recognize, he contacted Professor Dan Fisher of the Museum of Paleontology at the University of Michigan, who said he'd be "right out."

Accurate dinosaur color patterns detected (again)

Accurate dinosaur color patterns detected (again)

Dr Jakob Vinther began study on the colors of dinosaurs many years ago. His first study showed the color of the animal you'll see below this paragraph - a dinosaur by the name of Anchiornis huxleyi. This is the first accurately-colored dinosaur in the world, based on fossil melanin. The method used with study started back in 2006 included animals with feathers. Now a new study has surfaced (also including Vinther) that further substantiates the idea that melanin remains well-preserved enough to reconstruct color patterns on ancient animals - like dinosaurs.

Arctic Dinosaurs Discovered in Icy “Lost World”

Arctic Dinosaurs Discovered in Icy “Lost World”

While paleontology is done in warm climates today, some of the most interesting dinosaur bones reside northward, in the Arctic. In the Prince Creek Formation of Alaska, a team of researchers has discovered a sort of "lost world" of dinosaur bones in the ancient North of Alaska. Earlier today we discussed how Florida State University professor Greg Erickson and his team went about classifying a new type of dinosaur in this region. Now we're going to hear him speak about the creature and its environment.

Alaskan duck-billed dinosaur find spurs physiological mystery

Alaskan duck-billed dinosaur find spurs physiological mystery

A set of duck-billed dinosaur bones has been found in an environment where it'd never previously been discovered. All the way up in Northern Alaska, at Colville River, at a site called the Prince Creek Formation. "The finding of dinosaurs this far north challenges everything we thought about a dinosaur’s physiology," said Florida State University professor of biological science Greg Erickson and his colleagues. "It creates this natural question. How did they survive up here?" Also, is this the same Hadrosaur we already know and love?

Dinosaur footprints found strolling a German beach together

Dinosaur footprints found strolling a German beach together

Biologists uncover dinosaur tracks in formation with one another, suggesting carnivores walked amongst one another. What these ca. 50 footprints suggest, say biologist Pernille Venø Troelsen, is that these prints could have belonged to "two social animals, perhaps a parent and a young." These tracks were first revealed to the public back at this year's XIII Annual Meeting of the European Association of Vertebrate Paleontologists in Opole, Poland. It was there that Troelsen first showed the prints excavated between 2009-11 in a Bückeberg Formation in Münchehagen in Germany.
