Dinosaurs May Have Had Babysitters

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:

'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

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

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'

The debate on just where dinosaurs fall has raged for years, but in this study scientists looked primarily...

Saudi Arabia Milestone: Dinosaur Fossils

Scientists find first that can be identified in Arabian Peninsula

Before T. Rex, This Dinosaur Was King

Siats meekerorum is 3rd-biggest predator ever found on this continent
