Did Dino Meat Taste Like Chicken?

Probably not, and here's why

(Newser) - Turns out T. Rexes liked to eat other T. Rexes —so the obvious next question is, what does a T. Rex taste like? Not like chicken, writes Brian Palmer on Slate . But birds are related to dinosaurs, and it’s probably another bird—the hawk—that dinosaur meat is...

Tasty Snack for T. Rex: Another T. Rex

Paleontologist finds evidence of cannibalism

(Newser) - It looks like T. Rex was a cannibal. So says a Yale paleontologist who found telltale bone gouges on a fossil of the giant dinosaur that make it all but certain it had been eaten by a fellow T. Rex. That prompted him to take a closer look at other...

Dino Birth Pushed Back 9M Years

Just-discovered species walked the Earth 250 million years ago

(Newser) - Researchers analyzing footprints in 250 million-year-old Polish rock say they've identified the oldest dinosaur-like species ever discovered. Prorodatcylus walked on four legs, was about the size of a house cat, and lived in the shadow of its "more diverse, successful, and abundant crocodile-like cousins" for millions of years, according...

Utah's 'Lost World' Yields 15-Horned Dino

Kosmoceratops resembled oversized rhino

(Newser) - A pair of dinosaur species discovered in Utah rank among the horniest beasts ever to walk the Earth, researchers say. One, Kosmoceratops, had 15 full-sized horns on its head, which was roughly 6.5 feet long. Researchers believe the impressive display helped the dinosaur compete for mates, much like peacock...

Hump-Backed Feathered Dino Discovered

Mystery dinosaur offers link to first birds

(Newser) - It had a mysterious hump over its pelvis and feather-attachment bumps on its forearms: Meet the newly discovered Concavenator corcovatus, a dinosaur scientists hope will offer clues about the emergence of the first birds. Paleontologists unearthed the dino, a member of the theropod family, in central Spain. And while its...

Thousands-of-Years-Long Meteor Shower Killed Dinos

Study: There were many meteor strikes, not one

(Newser) - Some scientists believe a single meteor strike in the Gulf of Mexico doomed the dinosaurs, but new research suggests that the dinosaurs may have been wiped out by a meteor shower that lasted thousands of years, finds the Telegraph . A recent study of a crater in Ukraine, which dates much,...

Triceratops 'Never Existed'

Three-horned fossils are actually juvenile torosauruses

(Newser) - One of the best-known dinosaur species may not have really been a dinosaur species at all, according to new research. Scientists compared triceratops skulls to those of a lesser-known species, the torosaurus, and concluded that the triceratops were actually young torosauruses, New Scientist reports. They believe the three-horned dinosaur's skull...

Dwarf Dinos Island Hopped to Europe

'Mini-Triceratops' upends old theories

(Newser) - Dwarf dinosaurs may have made their way from island to island in the days when Europe was just a series of iles dotted in the prehistoric Tethys Ocean, according to scientists puzzling over bones found in a Hungarian coal mine. The bones belong to a small horned dinosaur from the...

Volcano Eruptions Led to Rise of Dinosaurs

The lava all but wiped out main competitors

(Newser) - An explosion of volcanic activity 200 million years ago may have been responsible for the mass extinction that left dinosaurs with few competitors and allowed them to dominate the Earth for almost 150 million years. Researchers have discovered evidence of massive lava flows concurrent with elevated levels of CO2 in...

Dino-Eating Snake Makes Hiss-tory

Serpent preyed on titanosaur babies

(Newser) - Hundred-ton dinosaurs may have been just as scared of snakes as humans are. The recent discovery of a fossilized snake wrapped around a baby titanosaur offers the first-ever direct evidence that prehistoric snakes fed on dinosaur hatchlings. Researchers believe the snake was attacking a baby dinosaur as it hatched; a...

Sea Once Filled With 'Dino Fish'

Giant fish prowled oceans in dinosaur age

(Newser) - Scientists have discovered a "missing link" in evolutionary history: evidence that prehistoric seas were filled with enormous, plankton-eating fish. The dino-sized fish existed between 66 and 172 million years ago, dying out around the the same time as the dinosaurs. It was only after they vanished that mammals and...

How Birds, Crocs Escaped Prehistoric Extinction

One-way breathing pattern points to common ancestor

(Newser) - In the midst of the planet's worst-ever wave of extinction some 250 million years ago, the ancestors of birds and alligators managed to survive thanks to a shared breathing mechanism that enabled them to weather low oxygen levels. New research shows that when birds and alligators breathe, air flows in...

Scientists Find Evidence of Poisonous Dinosaur

Sinornithosaurus had grooved teeth, room for poison gland

(Newser) - As if three-inch teeth don't sound deadly enough, at least one dinosaur may have delivered poison through those chompers. Two paleontologists examining the fossil remains of the Sinornithosaurus, a turkey-size cousin of the velociraptor, noticed it had grooved teeth, much like those on venomous lizards or snakes. Upon closer inspection,...

Dinosaurs Arose in S. America

Fossil of T. rex cousin helps fill in the puzzle

(Newser) - The fossil of a feisty little ancestor of T. rex lends credence to the theory that dinosaurs emerged in South America. More precisely, they likely arose about 230 million years ago in Pangaea, which was then the single joined continent of the Americas. The development follow the discovery of a...

100M Years Ago, Africa Was Crocodile Central

3 new species unearthed from Sahara include DogCroc

(Newser) - The universe of diverse prehistoric crocodile species keeps expanding, suggesting crocs were one of the dominant forms of life 100 million years ago. Paleontologists have just unearthed three new species in the Sahara desert: the 20-foot BoarCroc, which likely fed on dinosaurs; the 20-foot PancakeCroc, a flat-bodied fish-gobbler; and the...

Scientists Find Ancestor to Giant Dinosaurs

It's a link between smaller bipeds and huge quadripeds

(Newser) - Paleontologists in South Africa have found a new dinosaur, a sort of missing link between smaller two-legged creatures that dined on plants and the long-necked carnivorous giants of Jurassic Park. The new species, aardonyx celestae, was 20 feet long and walked on two feet. But crucially, it was able to...

Fossil Hunter Finds Giant Sea Monster

Colossal pliosaur was big enough to snack on T. Rex

(Newser) - A sea monster big enough to have munched on T. Rex has been found by an amateur fossil collector scouring Britain's south coast. The collector gathered chunks of the prehistoric beast's 8-foot-long skull as they fell from a cliff face over several years. Paleontologists believe the pliosaur skull is the...

'Ballerina-Like' T. Rex Cousin Discovered

Size, light skeleton and delicate teeth suggest different prey from larger relative

(Newser) - A smaller, more agile cousin of the Tyrannosaurus rex has been identified. The skull and a nearly complete skeleton of Alioramus altai was discovered in Mongolia in 2001, and has features that distinguish it from its more lumbering cousin. Unlike its “big bad boy” relatives, a study author tells...

Oldest Feathered Dino Found in China

Dinosaur is earliest known feathered species, may have flown on four wings

(Newser) - A fossilized creature found in northern China puts an end to any controversy over whether birds descended from dinosaurs, say Chinese scientists. The dinosaur, who lived some 10 million years before Archaeopteryx, is the oldest feather species ever discovered. The feathers cover its arms, tail, and also its feet, leading...

Pint-Size T-Rex Surprises Scientists

'Raptorex' was 1/100th the weight of its descendant

(Newser) - Paleontologists have unearthed a miniature predecessor of Tyrannosaurus Rex, a finding that may rewrite the origins of the most iconic of dinosaurs. “Raptorex,” discovered in China, has all the distinctive features of a Tyrannosaurus—large head and jaws, long legs, and small arms—but it weighed only 150...
