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.
Fossil teeth are more commonly between 3 and 5 inches.
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 actualy grow. 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).
Regardless of the exact size, it was an impressive animal!
megalodons were a little larger than the modern day Whale Shark, and over twice as large as a Great White shark. Factors for extinction include changing ocean currents, the loss of it's main food source, competition with Killer Whales, and whale migration into arctic waters.
With teeth that could reach over 7 inches and a body more massive than a T-Rex, Megatooth sharks, particularly Carcharocles Megalodon, are undoubtedly the most infamous of all prehistoric sharks. Most paleontologists believe the Megatooth shark lineage dates back to the giant mackerel shark of the Paleocene, Otodus obliquus.
Each zone of the formation has Otodus teeth that are slightly more serrated over geologic time until they start looking like an early Carcharocles tooth. The teeth became more regularly serrated, the Otodus cusps got smaller, the crown got broader, and the overall size increased. A very rough chronology of Megatooth species, leading to the megalodon is shown below on the following table: This shows the lineage of the Megatoothed sharks leading to the Megalodon.
It s 7 1/4" (184 mm) slant height and was found by Vito Bertucci in South Carolina.
Body Size: The more reliable body size estimates go up to around 60 feet. The average size of a megalodon was around 33 feet. According to all of the scientific research, megalodon became extinct around 2.6 million years ago.
Once the Otodus teeth became mostly serrated, paleontologists renamed the serrated Otodus genus to the Carcharocles genus, and thus the Carcharocles genus arose. Paleontologists assigned each slight tooth change of the Megatooth shark to a new Carcharocles species. This lineage example is not complete, as it is missing the Kazakhstan specimens, but it shows the general broadening and cusp reduction.
Where the genus transition occurs depends on which paleontologist you ask. It's important to note that each species is the Megatooth shark, with a slight change in tooth form over different periods of time.
Some of these fossil whale bones of the Miocene and Pliocene show bite marks from megalodon teeth. did computer modeling of the Great White shark and C. They found the megalodon had a maximum bite force of around 182,000 Newtons (41,000 lbs). This high bite force verifies megalodon could have easily crunched up large whales.
