Non-avian dino eggs hatched slowly, over as many as 6 months, study finds

New Twist on Why Dinosaurs Got So Big So Fast

Those with funky-looking skulls grew most quickly

(Newser) - For years, paleontologists have theorized that many of the world's largest dinosaurs sported head ornaments (think horns, knobs, and crests) as a means of intimidation and defense, and that these giants evolved to be so big because size helped them be more effective killers. But now new research published... More »

Dinosaur Fossil Is One of the 'Saddest' Ever Found

Scientists Believe They've Found Fossilized Dino Brain

It would be a major first

(Newser) - Are we one step closer to Jurassic Park? Probably not, but researchers do believe they've found the first ever example of fossilized brain tissue from a dinosaur, National Geographic reports. The fossil was found on an English beach in 2004, but its unique trait—mineralized pieces of brain tissue—... More »

Bus-Sized Dino Comes With a Surprise

It suggests migration from South America, not Asia

(Newser) - An Australian sheep farmer has discovered a beast far bigger than he's ever handled—along with new clues as to how dinosaurs ended up Down Under. Paleontologists, together with dinosaur enthusiast/sheep farmer David Elliot, say they've uncovered a new monster of a dinosaur belonging to the titanosaur subgroup... More »

One of Most Complete T. Rex Skulls Ever Arrives at Museum

'An iconic specimen'

(Newser) - It may look like a giant rock right now, but inside is what dinosaur expert Jack Horner calls "one of the most significant" Tyrannosaurus rex specimens ever found, the AP reports.

What Roar? Some Dinosaurs Likely Cooed

They perhaps made 'closed-mouth vocalizations' like birds

Asteroid That Killed Dinosaurs Wiped Out Most Mammals, Too

Only about 7% survived, says study

(Newser) - The asteroid that took out the dinosaurs nearly claimed the planet's mammals, too. Researchers at the UK's Milner Centre for Evolution report in the Journal of Evolutionary Biology that 93% of mammals were wiped out around the same time, far more than originally thought. And those that did... More »

T. Rex May Have Had Lips to Hide Its Ferocious Teeth

That goes against the popular image of the dinosaur in 'Jurassic Park' and elsewhere

(Newser) - The image of a "ferocious-looking" Tyrannosaurus rex with a "permanent smile" of huge protruding teeth is taking a hit thanks to one Canadian paleontologist, Live Science reports. Robert Reisz says the T. rex, along with other theropods, actually had scaly lips covering its teeth. “When we see... More »

Dinos Were Going Downhill Even Before Asteroid Hit

Decline started tens of millions of years earlier, study says

Scientists Grow Chickens With Dinosaur Legs

'With one small modification, millions of years of evolution can be undone'

(Newser) - Scientists—presumably so preoccupied with whether or not they could, they didn't stop to think whether they should—have grown chickens with dinosaur legs, Phys.org reports. More accurately, a team at the University of Chile grew chicken embryos with dinosaur-like fibulas. In modern birds, the fibula is shorter... More »

For T. Rex, Size Originally Didn't Matter

Horse-sized ancestor reveals evolutionary path, and intellect came before size

(Newser) - Though one of the most well-known dinosaurs, Tyrannosaurus rex is actually somewhat of a mystery, having suddenly emerged as a fearsome beast some 80 million years ago. As a 20-million-year gap in the fossil record preceded T. rex, paleontologists have known little about its evolutionary path—until now. The discovery... More »
