To better understand the extinct giants, Qvarnström and his colleagues investigated overlooked fossils known as bromalites: remnants from the digestive system — aka dinosaur poop and vomit. The analysis, which took 10 years to complete, allowed the team to piece together why dinosaurs came to prominence. Information from fossilized poop helped researchers to understand how dinosaurs rose to prominence 200 million years ago. Grzegorz NiedzwiedzkiReconstructing dinosaurs’ riseThe authors came up with five phases to explain dinosaurs’ ascendancy: Their ancestors were omnivorous, eating plants and animals. The supremacy of the dinosaurs endured until an asteroid that struck off the coast of what’s now Mexico 66 million years ago doomed the dinosaurs to extinction.
