Placental mammals coexisted with dinosaurs for a short time before they went extinct. Reported by the University of Bristol.

66 million years ago, all non-avian dinosaurs became extinct due to a large meteorite that fell to Earth. After that, mammals began to dominate among land animals, but for a long time it was unclear to scientists whether placental mammals coexisted with the dinosaurs before the mass extinction, or whether they evolved only after the giant lizards died out.

Emily Carlyle and colleagues applied To the statistical analysis of the fossil record to explore this issue. In this, scientists were helped by the model they created, which made it possible to predict the approximate time of origin of a species or genus based on its first appearance in the fossil record. Similarly, based on the last appearance date, you can find out the time of extinction.

Primates (among them the ancestors of humans), lagomorph (rabbits and rabbits) and carnivores (dogs and cats) appeared shortly before the mass extinction of the dinosaurs and lived with them for some time. After an asteroid slammed into Earth, placental mammals diversified rapidly, probably because the dinosaurs lost competition.
