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.
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.
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.
By analysing the fossilised teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants for longer periods than their contemporary relatives.
