The new findings address a 30-million-year gap in our knowledge of dinosaur evolution during the first part of the Late Triassic period. “The research material was collected over 25 years. It took us many years to piece everything together into a coherent picture,

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

While it is not quite as big as a Tyrannosaurus rex skeleton, fossilized poop can help paleontologists recreate lost worlds. It can tell scientists what extinct animals like dinosaurs ate, but more importantly the role that they played in their environment.

Fossilized digestive material offers unparalleled insights into the dinosaurs' diets, feeding behaviors and parasites.
