to a dominance that lasted 165 million years has now been charted… in the fossilized poop and puke they left behind.– paleontologists have been able to give a more detailed look at the emergence of the dinosaurs with a level of detail we've never seen before.
Bones tell us a lot about dinosaurs. We can reconstruct their skeletons and figure out what they may have looked like, how they lived, and what sort of diet they may have relied on. "We can never be sure about extinct animals' diet and feeding behaviours if we do not look at bromalites," he explained."Sure, we can guess, but analyzing bromalites gives us direct evidence of what animals were eating. We found many surprises along the way that we would have never guessed from the record of fossil bones only."regurgitalites
"We were incredibly surprised by many of the findings! We found tiny insect remains in many coprolites, and in one coprolite the little beetles were found intact with the tiny legs and antennae still preserved," Qvarnström said., perhaps the first big theropod in the region, used its powerful bite to crush bones like a modern hyena.
"The way these herbivores were sampling all plants in the new flora, in contrast to the non-dinosaur herbivores which had been more specialized, must have been an incredible advantage under changing environmental conditions," Qvarnström told ScienceAlert.
