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.
R. bracheri from the Early Miocene was one of the most widespread species, with fossil teeth known from the European Paratethys and from Japan. The last records of Rolfodon are indeterminate teeth from the Early Pliocene of Japan. [2] R. goliath, from the Late Campanian of Angola's southern Benguela Basin, could grow to very large sizes. [6]

It was named after the video game Galaga due to a resemblance between its teeth and the spaceships in the game, [1] and Field Museum volunteer Karen Nordquist.
An analysis of a partially complete tail fin fossil shows that Cretoxyrhina had a lunate (crescent-shaped) tail most similar with modern lamnid sharks, whale sharks, and basking sharks. The transition to tail vertebrae is estimated to be between the 140th and 160th vertebrae out of the total 230, resulting in a total tail vertebral count of 70 ...
