Studying the physiology and ecology of whales, dolphins, and other marine mammals through methods ranging from molecular ecology to tracking the movements of individuals and populations using ...

Gorgonopsians were an extinct group of synapsids that lived during the Permian period, between 270 and 250 million years ago. They are part of the evolutionary lineage that eventually led to the first ...

These ancient creatures are the direct predecessors of one remarkable group: the mammals. Mammals, relatively recent additions to the evolutionary timeline, trace their inception to nearly 200 million ...

Pangolins, the world’s most trafficked mammals, frequently appear in wildlife seizures, yet there is no universal system for tracking or identifying individual animals. Researchers proposed what ...

The Vaquita, scientifically known as Phocoena sinus, stands as the world’s most endangered marine mammal. With less than 10 individuals estimated to remain in the wild, the situation is critical, and ...

Before dinosaurs walked the Earth and tens of millions of years before the first mammals appeared, distant mammal relatives with long, serrated canine teeth were the dominant carnivores on land.

The fossils include fragments of skull, vertebrae, and ribs, as well as a well-preserved femur, providing vital details on the diversification of what would become the first true mammals. Replica of ...

However, actively hunting adult mammals still marks a significant shift in the squirrels' behavior. The team observed the squirrels hunting California voles (Microtus californicus californicus ...

In the eye-opening study, researchers observed the squirrels actively hunting and eating other mammals, specifically California voles. It marks the first evidence that these supposedly vegetarian ...

Gorgonopsians weren't a direct ancestor of living mammals, nor did they give rise to the saber-toothed cats that existed until around 10,000 years ago. However, they were part of the wider ...

Despite not being particularly mammal-looking, the earliest true mammals began to rise about 200 million years ago, when dinosaurs were still roaming Earth. However, the therapsids still had ...

The origin of mammals is shrouded in mystery, but every fossil clue helps rewrite the story. A new discovery on a Mediterranean island is challenging what we know about when—and where—mammal ...
