When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which cause...
A dinosaur that wore its "heart" on its tail is providing new clues to how ecosystems evolved on the African continent during the Cretaceous Period some 100 million years ago, according to researchers...
When it comes to the final days of the dinosaurs, Africa is something of a blank page. Fossils found in Africa from the Late Cretaceous, the time period from 100 to 66 million years ago, are few and f...
Ancient dinosaurs were adorned in some amazing ways, from the horns of the triceratops to the plates and spikes of the stegosaurus. A newly discovered, bird-like dinosaur fossil from China contains ev...
Paleontologists have identified a new species of titanosaurian dinosaur. The research is reported in a paper published this week in the Journal of Vertebrate Paleontology and is funded by the National...
Scientists have long wondered what the earliest dinosaur relatives looked like. Most assumed they would resemble miniature dinosaurs, about the size of chickens, and walk on two legs.The discovery of ...
For decades, scientists have wondered what the earliest dinosaur relatives looked like. Most assumed that they would look like miniature dinosaurs, be about the size of a chicken, and walk on two legs...
Sequence data of biomolecules such as DNA and proteins, which provide critical information for evolutionary studies, have been assumed to be forever outside the reach of dinosaur paleontology. Protein...
New research on the teeth of fossilized dinosaur embryos indicates that the eggs of non-avian dinosaurs took a long time to hatch—between about three and six months. The study, led by scientists at Fl...
One of the most well-recognized Cretaceous fossils is Citipati osmolskae (MPC-D 100/979), an oviraptorid dinosaur discovered in brooding position on a nest of unhatched eggs. The original description ...
Were dinosaurs fast, aggressive hunters like those in the movie "Jurassic World"? Or did they have lower metabolic rates that made them more like today's alligators and crocodiles?For 150 years, scien...
The study was led by John Eiler, the Robert P. Sharp Professor of Geology and professor of geochemistry, and Rob Eagle, a former Caltech postdoctoral scholar now at UCLA. A paper descri...
Globular clusters – dazzling agglomerations of up to a million ancient stars – are among the oldest objects in the universe. Though plentiful in and around many galaxies, newborn examples are vanishin...
A large international group of scientists, including an Oregon Health & Science University neuroscientist, is publishing this week the results of a first-ever look at the genome of dozens of common bi...
