A big problem with dinosaurs is that there seem to be too many meat-eaters. From studies of modern animals, there is a feeding pyramid, with plants at the bottom, then plant-eaters, and then meat-eaters at the top.
A new study led by Yale University confirms a long-held theory about the last great mass extinction event in history and how it affected Earth's oceans.

Scientists have discovered an extraordinary collection of fossils that reveal in detail how life recovered after a catastrophic event: the asteroid impact that wiped out the dinosaurs 66 million years ago at the end of the Cretaceous Period.
An international team of scientists, led by the University of Bristol, have produced an unprecedented record of the biotic recovery of ocean ecosystems that followed after the last mass extinction, 66 million years ago.
It takes ecosystems two million years to recover after a mass extinction and for them to become functional and resilient again, according to new UCL co-led research.
