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.
