It was about six inches long from head to tail, a furry, shrew-like tree-climber that ate insects and maybe worms, and probably hid out during the day to stay away from marauding dinosaurs. This small ...

A groundbreaking new research project has analyzed the evolution of the placental mammal skull using 3D scans of 322 specimens housed in more than 20 international museum collections, and crafted a ...

Resolving the timing and pattern of early placental mammal evolution has been confounded by conflict among divergence date estimates from interpretation of the fossil record and frommolecular-clock ...

Emily Carlisle receives funding from the University of Bristol. If you were asked to think of a mammal, chances are high you would think of a placental mammal – horses, dogs, cats, humans, even bats ...

A tiny, furry-tailed creature is the most complete picture yet as to what the ancestor of mice, elephants, lions, tigers, bears, whales, bats and humans once looked like, researchers say. These new ...

A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a ...

Clade age and extinction time estimates for placental mammal families. Each line represents a family (arranged by order and clade but without further phylogenetic information), with 95% credible ...

New fossils of a chipmunk-sized animal that lived about 85 million years ago suggest that placental mammals arose much earlier than is generally believed and thrived for millions of years alongside ...
