Researchers believe that fossilized feces and vomit from dinosaurs are shedding light on how the ancient creatures evolved to become dominant on Earth. A recently published study analyzed hundreds of fossilized digestive materials from the Triassic period.

Feces, vomit and fossilized food from inside stomachs have provided new clues into how dinosaurs rose to dominate Earth, a new study revealed on Wednesday.

Discover how fossilized poop, or coprolites, unveils fascinating insights into what dinosaurs ate 200 million years ago.

The way the dinosaurs relinquished their long dominance is well known. An asteroid struck Earth 66 million years ago, triggering a horrific mass extinction. But the way the dinosaurs - modest creatures initially - came to supremacy is less well understood.

Paleontologists at the University of Uppsala in Sweden studied more than 500 pieces of fossilized dinosaur poop to find out how dinosaurs evolved.

Scientists have charted how dinosaurs rose to prominence using a pretty unconventional method. They studied, in dirty detail, hundreds of samples of fossilized poop and vomit.

Studying bromalites helped paleontologists piece together how the reptiles came to rule a part of the prehistoric world.

When the Earth's climate changed millions of years ago, dinosaurs were more adaptable to new food sources than their picky non-dinosaur neighbors, researchers say.

Scientists are using used fossilized feces and vomit from Poland to reconstruct how dinosaurs came to dominate the Earth.

A study of fossilized feces and vomit attempts to piece together why dinosaurs were so evolutionarily successful.
