When studying muscle strain during jaw opening in three dinosaur species, researchers found that the Tyrannosaurus rex could extend its jaw 90 degrees –- a skill that came in extremely handy for carnivorous predators.
Dinosaurs had an elaborate nasal passage to keep their unusually large bodies cool, protecting their brain from overheating.
Researchers from the University of Alberta recently discovered fossilized tail feathers and soft tissues of an Ornithomimus dinosaur that shed light on the evolution of modern-day birds such as ostriches and emus.
A newly discovered pig-snouted turtle, Arvinachelys golden, may help researchers fill in the gaps of turtle evolution.
New evidence suggests that periodic mass extinctions occurring over the past 260 million years are directly linked to comet or asteroid showers.
Multiple baby duck-billed dinosaurs, identified as Saurolophus angustirostris, were recently excavated from “Dragon's Tomb" in Mongolia.
Researchers from the University of Bonn suggest that a prehistoric mammal, Spinolestes, may have suffered from hair loss. This fungal disease is commonly seen in many of the species' modern descendants.
It turns out that Jurassic hunters may have really been the terrifying sprinters that Hollywood has made them out to be. New research has revealed that careful body temperature regulation had many dinosaurs 'running hot,' but only on sunny days.
Ancient birds had an intricate arrangement of muscles and ligaments that controlled the main feathers of their wings. This suggests that some were able to fly as well as modern birds.
When an asteroid impacted Earth 66 million years ago, many species, including dinosaurs, faced extinction. But a furry beaver-like species actually survived and became top dog in the newly available environment.
Using Maiasaura fossil bones, researchers recently revealed the most detailed life history of any dinosaur known.
Dinosaur extinction was caused by an asteroid impact 66 million years ago that also triggered a series of volcanic eruptions, say researchers from the University of California Berkeley.
Crocodilians include a variety of modern and ancient alligators, crocodiles and their relatives. A team of researchers recently examined how the diverse species responded to past climate changes and how they might cope in the future.
A new hadrosaur species, a type of duck-billed dinosaur, was excavated from Alaska. This species represents the northernmost dinosaur known to date and likely endured dark winter months and snowy conditions, researchers say.
Editorial: While it's not a pit of tar in a Los Angeles park, it may be nearly as good in terms of providing a predator record of the Jurassic period. Paleontologists will continue to study this predator pit in Utah, first explored in 1928. Today they're using new technology, photogammetry.
