Newly Found Dinosaur Survived 'Horrific' Extinction

Tachiraptor fossils discovered in Venezuela

(Newser) - A newly discovered dinosaur in Venezuela may help us understand how species survived a mass-extinction event about 200 million years ago, phys.org reports. Based on two leg-bone fossils, paleontologists say Tachiraptor admirabilis was fairly small (5 or 6 feet, tip to tail), ran on two feet, and ate meat....

Mammals Have Been Around Way Longer Than We Thought

Squirrel-like Jurassic creatures tell story: researchers

(Newser) - A squirrel-like animal in the tree branches above would have been a familiar sight to some dinosaurs, researchers have learned.

Giant Shark-Eating Dinosaur Found

Spinosaurus was able to swim, say researchers

(Newser) - Move over, T. rex: Fossils unearthed in the Sahara Desert have revealed that Spinosaurus was not only a bigger carnivore, it dined on giant sharks.

Dinosaurs May Have Had Babysitters

Researchers find fossils suggesting older sibling watched younger ones

(Newser) - Even dinosaurs need a babysitter—or would that be dino-sitter? Researchers say a group of hatchlings found in a layer of rock might have been under the care of "a big brother or sister," the Philadelphia Inquirer reports. The 120-million-year-old Psittacosaurus bones were found in northeast China, the...

Meet Dreadnoughtus, Biggest Dinosaur Yet

One in Patagonia weighed 65 tons, was still growing

(Newser) - Introducing the new king of the dinosaurs, at least in terms of size. Researchers in the Patagonia region of Argentina found a brute they've named Dreadnoughtus, and they're laying claim to it being the largest land animal whose size can be accurately measured—thanks mainly to the fact...

Mom: 'We don't have dinosaurs anymore'

Toothless 'Dragons' Roamed Our Skies

Pterosaurs were neither dinosaurs nor ancient birds but winged reptiles

(Newser) - A family of animals ruled the skies some 90 million years ago, but they weren't dinosaurs, and they weren't birds, and they didn't even have teeth. The winged reptiles of the late Cretaceous period belong to a family of pterosaurs called Azhdarchidae, and they appear to have...

10 Dinosaur Mysteries That Still Linger

Who was biggest and how they mated are still unknown

(Newser) - Dinosaur articles, movies, and museum displays are common enough that you might consider all dino-mysteries solved, but the Smithsonian reports that major ones still remain. Among them:
  • Who was first? Nobody knows which dinosaur species came first, partly because fossil records provide fragmentary insights rather than "the entire reel,

'Bad Timing' Wiped Out Dinosaurs

Asteroid hit at just the wrong time, researchers say

(Newser) - The huge asteroid that hit Earth 66 million years ago was very bad timing for the dinosaurs, a new study says—it wiped them out, but they probably would have survived if it had hit at a "more convenient" time. The impact in what is now Mexico is almost...

'Fantastic' Find Suggests All Dinos Had Feathers

Siberian fossils 'completely changed our vision of dinosaurs': researcher

(Newser) - Dinosaurs were scaly old things, right? Not so much, apparently. A Science study of 150-million-year-old fossils uncovered in Siberia is playing a big role in flipping that perception on its head, suggesting that nearly all dinosaurs actually sprouted feathers. At least five species of feathered dinosaurs have turned up in...

'Flying' Dino Had 4 Wings, Long Feathers

Turkey-sized raptor may have been expert glider

(Newser) - Take the velociraptors made famous by Jurassic Park, make them a bit smaller, add feathers, then change the limbs to wings and you will have something resembling a newly discovered dinosaur species found in China. Researchers say Changyuraptor yangi, a carnivore that lived around 125 million years ago, has the...

Thousands of 'world-class' hadrosaur prints discovered in Denali

(Newser) - Forget seeing Russia from Alaska: Scientists have found a trove of tracks left behind by dinosaurs that once roamed our northernmost state—and some of them are pretty big. A paleontology team discovered a "world-class" trail in the northeast corner of Denali National Park that was littered with thousands...

Triceratops Horns Were 1M Years in Making

Large nasal horn they are so famous for wasn't always so big

(Newser) - The rhino-like Triceratops, Greek for "three-horned face," didn't always embody its name in way we picture it doing. By comparing 50 skulls collected over a 15-year period from the Hell Creek Formation in Montana, paleontologists have learned that it took between 1 million and 2 million years...

Dino Grew 'Wings'— on Its Head

Mercuriceratops gemini used protrusions to attract mates

(Newser) - If you thought the " Pinocchio Rex " looked a bit odd, get a load of this dinosaur: Scientists have discovered a Triceratops relative, the smaller Mercuriceratops gemini, which sported bony "wings" on either side of its head. The fact that fossil fragments showing butterfly-like protrusions from the skull...

Were Dinos Cold-Blooded or Warm-Blooded? Neither

Scientists call for a new class called 'mesothermy'

(Newser) - A new study suggests that dinosaurs aren't either warm-blooded (endothermic) or cold-blooded (ectothermic) but rather a little bit of both, occupying a newly-described intermediate category scientists are calling "mesothermy." The debate on just where dinosaurs fall has raged for years, but in this study scientists looked primarily...

10K dinosaur species live on 'in form of birds,' says study author

(Newser) - How many dinosaur species roam the Earth today? "About 10,000 ... in the form of birds," says Oxford paleontologist Robert Benson, one of the authors of a study published in Plos Biology that clarifies dinosaurs' evolutionary path. As Astrobiology explains (and as you may be thinking), the belief...

Scientists: We've Found Biggest Dinosaur Ever

Figure about 130 feet long and 85 tons

(Newser) - Even by dinosaur standards, a new one unearthed in Argentina is big. In fact, the paleontologists who found it say it's the biggest ever found and thus the biggest creature ever to have walked the earth, reports the BBC . Let us count the ways: Based on its ginormous thigh...

New Dinosaur Was 'Chicken From Hell'

Tough, 10-foot beast roamed western US

Saudi Arabia Milestone: Dinosaur Fossils

Scientists find first that can be identified in Arabian Peninsula

(Newser) - A new fossil discovery confirms that dinosaurs roamed present-day Saudi Arabia. Researchers report in PLoS One that they found bone fragments of two different dinosaurs that lived about 72 million years ago. One is a distant cousin of T-Rex, a meat-eating theropod. The other is a plant-eating titanosaur, reports LiveScience...
