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.
The locality has also a high presence of sharks indicated by a large abundance of shark teeth; however, most of these teeth have not been identified. Megalodon teeth have been found in the bay, and evidence from bite marks in whale bones indicate the additional presence of the great white shark, shortfin mako and broad-toothed
With these remains, the study authors determined that Ptychodus belonged to the order of sharks known as Lamniformes, or mackerel sharks, the same group that the extinct Otodus megalodon and the ...
The megalodon, which went extinct 2.6 million years ago, is estimated to have been between 52 and 59 feet long, which is nearly three times the size of an average great white shark.
Comparative studies of the centrum radii and growth rings on the vertebrae of O. obliquus and the extant great white shark through X-rays have concluded that the sizes of the vertebrae at birth are similar, meaning that the offspring of both species would have the same size (between 1.1 and 1.6 m (3.6 and 5.2 ft) in length); they also revealed ...
The great white shark (Carcharodon carcharias) may have wiped out the giant megalodon (Otodus megalodon).Millions of years before human beings emerged, a type of shark that grew up to 60 feet (18 ...
