The rocks of the Karoo, deposited over a very long period from 300-180 million years ago, are internationally renowned for their wealth of fossils, particularly of therapsid reptiles which are the ...

Therapsids were a diverse bunch ... both groups lived side by side for millions of years, and both are reptiles in the broadest sense. But the key difference lies in their evolutionary paths.

This explanation implies that pelycosaurs were cold-blooded. From the pelycosaur line arose the therapsids, mammal-like reptiles that had faces and teeth resembling those of wolves. They were ...

This is typical of more advanced synapsids known as therapsids, or "mammal-like reptiles," Singh said, though it has never been seen before in a non-therapsid synapsid. When the fossil was fully ...

The fossil of the Euchambersia therapsid (a pre-mammalian reptile), that lived in South Africa about 260 million years ago, is the first evidence of the oldest mammal to produce venom. CT scans of ...

And these may have contributed to the subsequent evolutionary success of mammals. Therapsid reptiles are the distant ancestors of mammals, and they walked the Earth long before dinosaurs dominated.

Adding to the confusion, the well-defined fossil series that details the evolution of mammals from therapsid reptiles trails off around the time that monotremes split off from the rest of mammals ...

a group known as therapsids, which are the ancestors of all modern mammals, thrived even before the dinosaurs’ reign. The fossilised remains of a mammal-like reptile discovered in Poland reveal ...

“Lizards are a kind of reptile, and nonmammalian therapsids like gorgonopsians are part of a completely different evolutionary lineage, part of the lineage that includes mammals,” Angielczyk said.
