Megalodon teeth can measure over 180 millimeters (7.1 in) in slant height (diagonal length) and are the largest of any known shark species, [29]: 33 implying it was the largest of all macropredatory sharks. [35] In 1989, a nearly complete set of megalodon teeth was discovered in Saitama, Japan.
Otodus megalodon fossil shark jaw (reconstruction) (late Cenozoic) 2. A commonly referred to transition is the evolution of Isurus hastalis, the extinct giant mako, into the great white shark, Carcharodon carcharias. There exist teeth that are believed to represent the transition between the two species.
Otodus chubutensis was a large lamniform shark, with the largest individuals reaching a body length of 13.5 metres (44 ft). [9] Relatively large individuals reached body lengths of 9–11 metres (30–36 ft). [10] Smaller individuals were still about the size of the modern great white shark, reaching body lengths of 4.6–6.3 metres (15–21 ft).
Parotodus. Otodontidae is an extinct family of sharks belonging to the order Lamniformes. Its members have been described as megatoothed sharks. [1][2] They lived from the Early Cretaceous to the Pliocene, and included genera such as Otodus, including the giant megalodon. [3] Recent studies of the newly described genus Megalolamna indicate that ...
Otodus angustidens[1] is an extinct species of prehistoric megatoothed sharks in the genus Otodus, which lived during the Oligocene and Miocene epochs about 33 to 22 million years ago. [2] The largest individuals were about 11–12 metres (36–39 ft) long. This shark is related to another extinct megatoothed shark, the famous Otodus megalodon.
Hannibal & Jordan in Jordan, 1923. Otodus is an extinct, cosmopolitan genus of mackerel shark which lived from the Paleocene to the Pliocene epoch. The name Otodus comes from Ancient Greek ὠτ- (ōt-, meaning "ear") and ὀδούς (odoús, meaning "tooth") – thus, "ear-shaped tooth".
Otodus auriculatus[1] is an extinct species of large sharks in the genus Otodus of the family Otodontidae, closely related to the sharks of the genus Otodus, and also closely related to the later species megalodon. The largest individuals were about 9.5 metres (31 ft) long. Its teeth were large, having coarse serrations on the cutting edge, and ...
Ptychodus. Ptychodus (from Greek: πτυχή ptyche 'fold' and Greek: ὀδούς odoús 'tooth') [1] is a genus of extinct large durophagous (shell-crushing) lamniform sharks from the Cretaceous period, spanning from the Albian to the Campanian. [2] Fossils of Ptychodus teeth are found in many Late Cretaceous marine sediments worldwide.
