The Eocene Tologaysor (say that 3 times in a row) formation in Kazakhstan shows this transition nicely. It is clear the Megatooth shark lineage (Carcharocles) was born from the Otodus lineage. Over time the Megatooth shark went through slight morphological changes.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.
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.
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.
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!
As a result, there are many teeth that are a cross between two species. subauriculatus have large cusps, where by late Miocene the cusps are very small.
Some paleontologists may further subdivide the many C.
According to Gottfried, the weight of a huge 56 foot megalodon would have been around 65 tons (59 metric tons)!
Here are some size comparisons of a large 48 foot adult megalodon shark with teeth around 6 inches in slant height: Great White Shark: A megalodon was probaby around three times larger than a Great White Shark, which a length of 20 feet is rare.
The left one is intact, while the right one has been bitten in half by a C. Notice the large gouge marks where the teeth scraped through the vertebra.
