Scientists Discover 212-Million-Year-Old Crocodile Ancestor that Walked Upright and Had No Teeth
Paleontologists have described a new Triassic reptile, *Labrujasuchus expectatus*, nicknamed the “Witch Croc.” The 212‑million‑year‑old fossil from Ghost Ranch, New Mexico, walked on two legs, sported a toothless beak, and possessed tiny forelimbs. Its bipedal, beaked morphology is unprecedented among crocodile relatives and closely resembles later fast‑running dinosaurs. The find fills a long‑standing gap in the archosaur family tree, confirming a predicted evolutionary form.
