Restoration of the skeleton of O. megalodon based on modern lamniforms, with known elements highlighted. Megalodon is represented in the fossil record by teeth, vertebral centra, and coprolites. [35] [67] As with all sharks, the skeleton of megalodon was formed of cartilage rather than bone; consequently most fossil specimens are poorly ...
Dunkleosteus is an extinct genus of large arthrodire ("jointed-neck") fish that existed during the Late Devonian period, about 382–358 million years ago.It was a pelagic fish inhabiting open waters, and one of the first vertebrate apex predators of any ecosystem.
The Lamniformes also include the extinct megalodon, Otodus megalodon. Orectolobiformes: They are commonly referred to as the carpet sharks, including zebra sharks, nurse sharks, wobbegongs, and the whale shark. Pristiophoriformes: These are the sawsharks, with an elongated, toothed snout that they use for slashing their prey.

The hadrosaurus, discovered in Gloucester County in 1838 by John Estaugh and Joseph Leidy, was the first relatively complete dinosaur skeleton found anywhere in the world.
Livyatan and megalodon were likely the apex predators of this area during this time. [24] [29] Reconstruction of Livyatan (left) next to Cetotherium (right) L. melvillei is also known from the Bahía Inglesa Formation of Chile, whose fossiliferous beds are dated between the Tortonian and Messinian 9.03–6.45 mya. Like the Pisco Formation, the ...
These estimates varied depending on the girth of its rib cage and the amount of soft tissue modelled around the skeleton, with an overall average weight of 5.9 metric tons (6.5 short tons), and a lowermost estimate with minimal body fat and other tissues at 4.9 metric tons (5.4 short tons) and a maximum of 7 metric tons (7.7 short tons) at its ...
