Scientists found a new species of early crocodile relative that lived on land and moved quickly through vegetation. It was discovered in Gloucester, UK, around 215 million years ago.

Imagine a creature that's half-crocodile, half-greyhound. That's what scientists have discovered in ancient Britain. This newly identified species is called Galahadosuchus jonesi. It lived on land and was built for speed, with long, slender legs and a lightweight frame. This means it likely moved quickly through vegetation, hunting small reptiles, amphibians, and early mammals.

Galahadosuchus jonesi was found in Gloucester, UK, around 215 million years ago. At that time, this region was an elevated landscape surrounded by hot, dry plains. The species name combines a nod to Arthurian legend with a personal tribute to David Rhys Jones, a schoolteacher who taught the study's lead author.

The fossil remains were recovered from fissure deposits located on both sides of the Bristol Channel in southern Wales and southwest England. These deposits formed when animals that died on the surface were washed into underground cavities, where they were eventually buried by sediment.

Why It Matters

This discovery helps us understand ecosystems that existed just before a major extinction event. By studying which species lived before this event and how they responded to environmental changes, researchers can gain insight into how life adapts during periods of major upheaval.
