According to a new 3D modeling study published in Science Advances, the extinct giant shark, Otodus megalodon, could reach body sizes and speeds much greater than previously imagined.
So far, only megalodon's teeth and some vertebrae have been discovered due to their skeletons being made of cartilage which does not fossilize well. Therefore, the size and shape of other components of the megalodon’s anatomy inferred from these fragments remain questionable — and in some cases, outdated. For example, the study highlights that the megalodon’s body mass was last estimated in the early 1990s and was based on the now disfavored assumption that C.
The new study reconstructed a 16-meter O. megalodon using an exceptionally well-preserved fossil to create the first three-dimensional model of its body. The study also challenges what was previously known about the apex predator’s ‘cruising’ speed and feeding habits.The resulting model suggests that the megalodon had a body size of approximately 15.9 meters — considerably longer than a previous estimate of 9.2 meters.
