Plesiosaurs Swam Like Penguins

Simulation resulted on a swimming movement of Plesiosaurs as penguin-like. The plesiosaurs has something in common with the penguins. Both creatures share the same mechanical movements when it comes to swimming.

Were Dinosaurs Warm Blooded Like Modern Animals?

For years the accepted theory was that dinosaurs were cold blooded, much like modern reptiles today. However, a study then showed that they were neither cold blooded or warm blooded like animals today. However, a paleontologist revisited that study focusing on the metabolism and growth of the dinosaurs. The re-analysis then provided evidence that dinosaurs were actually warm blooded like many of today's modern animals.

Dino Debate Continues – New Analyses Indicate They Were Warm Blooded

In the long debate over whether dinosaurs were warm or cold blooded, a study published last year in Science was thought to have put the issue to rest. Dinosaurs were neither, according to the paper. Instead, they occupied an intermediate category. But a reanalysis of the same data has drawn new conclusions. And the verdict this time? Warm blooded.

Meet Velociraptor’s ‘Nosey’ Cousin

Paleontologists have recently identified a new member of the raptor family, one that may have had a leg up on its competition: a keen sense of smell.

Embryological Manipulation Reveals Chicks Can Have Prehistoric Looks

One of the latest breakthroughs from Yale scientists: the mighty dino-chicken. The Yale team used molecular manipulation to grow chicken embryos with Velociraptor snouts and published their results yesterday in the journal Evolution. The embryos did not hatch.

Can Dinosaur Skulls Tell Us Just What They Ate and How?

With recent archaeological findings proving that researchers may not know as much about prehistoric life as they once thought, researchers with the American Museum of Natural History are taking another look at interpreting the diets of long-extinct animals, and what they’re finding points to finding the source of a prehistoric diet. Though teeth shape has been used for decades as a primary indicator as to the dietary habits of a fossilized subject, in a new study published today in the journal PLOS ONE, researchers are now saying that skull shape and ancestral lineages, both before and after extinction events, may serve as a proxy for what these animals truly once ate.

More than Meets the Eye—T Rex Relative Was Herbivore Instead

In the world of dinosaurs, not everything was as it seems. The most advantageous appendages may have just been for show-and-tell, to ward off unassuming predators, and some of the most evolutionarily superb tricks may never be revealed in the fossils we find today. And with the endless wonder of discovering an entirely unique world, unlike our own, paleontologists, like children, keep learning in the hopes of one day adding their own discovery into the dialogue. The only difference is that one of these differences was recently discovered in a new species of dinosaur related to the Tyrannosaurus rex, but this discovery really was made by a child—seven-year-old Diego Suárez.

Scientists Digging Deep Into Dinosaur Killing Crater

The catastrophic impact that ended the reign of dinosaurs on Earth has long been of interest to scientists around the world. In an attempt to learn more about what happened 65 million years ago, scientists plan to drill some 5,000 feet deep into the Chicxulub Crater, the lasting scar from this world changing event.

Getting to the Core of Extinction—Researchers Return to Crater That Caused Millions of Dinosaurs to Die

It’s no big surprise as to why we exited the Jurassic period. The dinosaurs and their lineage ended with a shocking crash when a catastrophic asteroid plummeted to Earth, and dust and debris blocked out the Sun. But now researchers are hoping that by going back to the site of the impact they may be able to learn a bit more about ancient biological and geological processes, and perhaps even what cosmic changes led to the asteroid’s impact.

The Miracle of Birth of the Ancient Mosasaurs

A new study published in the journal Palaeontology has revealed some interesting new details about the process of reproduction in Mosasaurs, the large marine lizards that once populated the waters about 65 million years ago.

With a Bit of Luck and Inspiration, One 4-Year-Old Boy Found a Dinosaur in Texas

Think that you don’t have what it takes to start a career in paleontology, even though your fascination with dinosaurs never ends? Well never fear, news this week reveals that you’re never too old, or too young, to start on the hunt for dinosaurs. And 4-year-old Wylie Brys, of Mansfield, Texas, is proving this sentiment true.

Reptile Preceding Dinosaurs Discovered

Paleontologists have discovered a new species of reptile after putting together the remains of a new crocodile-like species that lived long before dinosaurs roamed the Earth.

Researchers in Scottland Find Remnants of Nessy’s Relatives—Or So It Seems

While tales of the cryptid, the Loch Ness monster more colloquially known as Nessy, have gone largely unsubstantiated in the past, archaeologists in Scotland believe that they may now have found creature that fits the bill. The only problem is, that the dolphin-like marine reptile which grew to lengths of up to 14 feet went extinct nearly 170 million years ago.
