For some historical creatures, scientists have complete skeletons with which to reconstruct what the animals might have seemed like in life. However for the megalodon, the duty is way more troublesome.
The fossil document solely comprises vertebrae, tooth, scales, and a few fragments of cartilage from megalodon. Some paleontologists have used tooth or the vertebral columns of nice whites to determine how huge the traditional shark may need been. However complete parts of megalodon stay a thriller—together with the top, tail, and fins. (So if you happen to’ve ever gotten your image taken in entrance of a megalodon jaw at a museum, you had been standing in entrance of a finest guess, as a result of no jaw for the meg has ever been discovered.)
To fill within the gaps, Shimada and his colleagues developed a brand new methodology to estimate the physique size of the leviathan, utilizing a virtually full vertebral column from Belgium and one other incomplete vertebral column from Denmark. By evaluating them to the physique plans of 170 different shark species, each residing and extinct, they then had been in a position to estimate how massive that individual megalodon’s head and tail would have been—about six toes (1.8 meters) and 12 toes (3.6 meters) lengthy. In whole, this is able to have made the Belgian megalodon specimen 54 toes (16.4 meters) lengthy.
Nevertheless, as a result of one of many vertebrae belonging to the Denmark discover was significantly greater than the most important vertebrae within the Belgian backbone, the scientists may then scale up their estimates to reach on the new, breathtaking whole size.
