Shark teeth dating
With that said, no one is sure what the body of the megalodon shark looked like. Using tooth and jaw reconstructions from associated fossils, paleontologists have calculated possible size estimates.Therefore it is difficult to say how big the megalodon shark could get. Some estimates (Pimiento & Balk 2015) give a megalodon a maximum average length of around 59 feet (18 m), while other estimates are a little higher, such as 66 feet (20.2 m) (Gottfried et al. The average size of a megalodon was around 33 feet (10 m).The teeth became more regularly serrated, the Otodus cusps got smaller, the crown got broader, and the overall size increased. The megalodon shark became extinct during the Pliocene and left no next of kin; the megalodon became too large and too specialized for its own good. A very rough chronology of Megatooth species, leading to the megalodon is shown on the following table: It's important to note that each species is the Megatooth shark, with a slight change in tooth form over different periods of time.
Where the genus transition occurs depends on which paleontologist you ask. Over time the Megatooth shark went through slight morphological changes.
An example of megalodon predation evidence is shown in the images below. For comparison T-Rex has been calculated to have a maximum bite force around 57,000 Newtons (13,000 lbs).

Whale Shark: A megalodon was probably slightly larger than a Whale Shark, which can reach lengths around 41 ft.
Blue Whale: A megalodon was probably about half the size of a Blue Whale, which can reach lengths of around 94 ft.
