The behemoth clocked in at a whopping 6 1/6 inches in length—roughly the size of a human hand!
Ptychodus was a large shark, previously estimated at 10 meters (33 feet) long based on extrapolation from teeth. [ 13 ] [ 14 ] The subadult specimen with the largest vertebra showed that it could reach lengths of 4.3–7.07 m (14.1–23.2 ft), so a 10 m (33 ft) length is possible, but more analysis is required for verification.
The pieces are now reunited, creating a single 5.5-inch-long, 5.1-inch-wide tooth that came from one of the world’s most fearsome predators — a prehistoric shark that reached nearly 60 feet in ...
