The “Carolina butcher” has been found and is just as scary as the name suggests.

Scientists on March 19 said they had unearthed fossils in North Carolina of a big land-dwelling croc that lived about 231 million years ago, walked on its hind legs and was a top land predator right before the first dinosaurs appeared.

Transported back to the Triassic Period, what would a person experience upon encountering this agile, roughly 3-meter-long, 1.5-meter-tall beast with a long skull and blade-like teeth?

“Abject terror,” said North Carolina State University paleontologist Lindsay Zanno, who led the research.

“Climb up the nearest tree,” advised North Carolina Museum of Natural Sciences paleontologist Vince Schneider.

The creature is named Carnufex carolinensis, meaning “Carolina butcher,” for its menacing features. It was a very early member of the croc lineage and was unlike today’s crocs.

It was not aquatic and not a quadruped, instead prowling on two legs in the warm equatorial region that North Carolina was at the time.

It lived alongside armoured plant-eating reptiles known as aetosaurs, early mammal relatives and other fierce predators such as the large, long-snouted, water-dwelling, four-legged phytosaurs.

Carnufex is one of the most primitive members of the broad category of reptiles called crocodylomorphs, encompassing the various forms of crocs that have appeared on Earth.

“As one of the earliest and oldest crocodylomorphs, Carnufex was a far cry from living crocodiles. It was an agile, terrestrial predator that hunted on land,” Zanno said.

The scientists unearthed portions of Carnufex’s skull, spine and forelimb parts from a Chatham County quarry. Then also created a three-dimensional model of the skull, filling in the missing parts with the more complete skulls of close relatives.

Carnufex lived just before the appearance of the first dinosaurs, which started as modest creatures in the Triassic.

Zanno said Carnufex’s discovery underscores the notion that before dinosaurs became well established in North America, such crocs and their cousins filled the large predator roles.
