A newly described fossil from South Australia is making waves in our understanding of where and when whales evolved titanic body sizes.
The fossil deposits at the La Brea Tar Pits in Los Angeles have well-preserved remains of many prehistoric animals that got stuck in natural asphalt seeps over the past 60,000 years.

New findings from the La Brea Tar Pits in southern California suggest human-caused wildfires in the region, along with a warming climate, led to the loss of most of the area’s large mammals.

Polar bears and wolves may get the glory, but small predators like weasels, foxes and their cousins play outsized ecological roles. And many of these species are declining fast.
A peculiar giant kangaroo that once lived in New Guinea would have descended from a much more ancient form that migrated from Australia, between 5 million and 8 million years ago.
Genyornis newtoni was one of the biggest birds ever to walk the earth. And new research shows its mysterious extinction may have come amid a bout of widespread bone disease as its lake home dried out.
The famous deaths of moas and dodos has fed a narrative in which humans are agents of extinction for island-dwelling animals. But research suggests this only recently became the case.
