Bromalites show how dinosaurs rose to rule Earth

By analysing fossils of poo and vomit, researchers have reconstructed what dinosaurs ate and how this changed over time. The findings give a better understanding of how dinosaurs became so dominant, revealing that their rise, over millions of years, was influenced by factors including climate change-induced shifts in what vegetation was available, which the dinosaurs were able to adapt to better than other animals. The contents of the fossils became more varied over time, suggesting that larger dinosaurs with more diverse feeding habits began to gain prominence in the late Triassic period a little over 200 million years ago.
