The discovery of a nearly complete dromaeosaurid Saurornitholestes langstoni specimen is providing critical information for the evolution of theropod dinosaurs, according to new research.
Read moreDifferent dinosaur groups independently evolved gigantic body sizes, but they all faced the same problems of overheating and damaging their brains.
Read moreResearchers have uncovered evidence of the storage and delayed consumption of animal bone marrow at Qesem Cave near Tel Aviv. The research provides direct evidence that early Paleolithic people saved animal bones for up to nine weeks before feasting on them inside the cave.
Read moreFossils discovered in Thailand represent a new genus and species of predatory dinosaur, according to a new study.
Read moreAn international research team has discovered a new and well-preserved fossil stingray with an exceptional anatomy, which greatly differs from living species. The find provides new insights into the evolution of these animals and sheds light on the recovery of marine ecosystems after the mass extinction occurred 66 million years ago.
Read moreTo study the diet of ancient crocodiles, two researchers combined mathematical analyses of the animals' shapes, surveys of modern crocodiles' diet, modeling methods for reconstructing the diet of fossil groups, and forensic-style interpretations of damaged bones from the distant past.
Read moreA Tyrannosaurus rex could bite hard enough to shatter the bones of its prey. But how it accomplished this feat without breaking its own skull bones has baffled paleontologists. That's why scientists are arguing that the T. rex's skull was stiff much like the skulls of hyenas and crocodiles, and not flexible like snakes and birds as paleontologists previously thought.
Read moreAn evolutionary biologist has spent more than three decades studying the skulls of many species of large carnivores — including wolves, lions and tigers — that lived from 50,000 years ago to the present. She reports today the answer to a puzzling question.
Read moreFiguring out what lies ahead for our species and our planet is one of the most pressing and challenging tasks for climate scientists. While models are very useful, there is nothing quite like Earth's history to reveal details about how oceans, animals, and plants respond to and recover from a warming world.
Read moreScientists have evaluated fossil color reconstruction methods and proposed a new study framework that improves and expands current practice.
