The decline of species richness from equator to pole, or latitudinal diversity gradient (LDG), is nearly universal among clades of living organisms, yet whether it was such a pervasive pattern in the ...

Mammal species diversified more rapidly early in their history – peaking roughly 66 million years ago – before a long-term decline in diversification punctuated by diminishing bursts of evolutionary ...

New research has examined the fossil record going back 66 million years and tracked changes to mammalian ecosystems and species diversity on the North American continent. When trying to understand the ...

Recently announced findings, published in the journal Science by Maureen O’Leary and colleagues, represent an important step in understanding the early evolution of placental mammals, and sheds light ...

Although they came into their own only after the extinction of the dinosaurs some 65 million years ago, mammals had maintained a low-profile existence for some 150 million years before that. New ...

After the dinosaurs disappeared, the world saw an explosion of birds and mammals. But a study suggests a burst of new snakes appeared, too, with diets to match the newly expanding array of animals.

LAWRENCE -- A $100,000 grant from the David B. Jones Foundation will help to develop a new generation of paleontologists at the University of Kansas, enabling students to pursue fieldwork in locations ...
