Well-preserved skeleton reveals the ecology and evolution of early carnivorous mammals

Prior to the rise of modern day mammalian carnivores (lions and tigers and bears, as well as weasels, raccoons, wolves and other members of the order Carnivora), North America was dominated by a now extinct group of mammalian carnivores — the hyaenodontids.

High-tech analysis of proto-mammal fossil clarifies the mammalian family tree

A new analysis of the jaw of Haramiyavia clemmenseni, one of the earliest known proto-mammals, clarifies the timeline of early mammalian evolution. Through high-resolution computer tomography, scientists from the University of Chicago, Harvard University and Brown University were able to examine the Haramiyavia type specimen in unprecedented detail. The analysis revealed complex teeth and chewing … Continue reading

Jurassic saw fastest mammal evolution

Mammals were evolving up to ten times faster in the middle of the Jurassic than they were at the end of the period, coinciding with an explosion of new adaptations, new research shows. Early mammals lived alongside the dinosaurs during the Mesozoic era (252-66 million years ago). They were once thought to be exclusively small … Continue reading
