Abstract in brief
The study aims to estimate the body size and shape of the extinct giant shark Otodus megalodon by comparing it to several modern sharks that are similar in ecology and physiology, instead of just relying on the great white shark as a reference.
The researchers found no evidence of allometry (size-related shape changes) among the modern analogs, allowing them to confidently extrapolate the body dimensions of O. megalodon at different sizes, suggesting that a 16-meter-long O. megalodon likely had a head around 4.65 meters, a dorsal fin about 1.62 meters tall, and a tail approximately 3.85 meters high.
Morphometric analyses indicate that O. megalodon's fins were adapted for swift movement and long-distance swimming, supporting its role as an efficient predator capable of powerful, sustained locomotion.
First, research by @CooperPalaeo, @pimientoc, @Ferron_HG & Mike Benton @BristolPalaeo used living sharks to estimate individual megalodon body dimensions – among their results, they found that a 16 m megalodon had a dorsal fin as tall as a human adult! https://t.co/fkIYCsrIPC
