A new study bases its calculations on more than the great white shark.
09 September, 2020
- Previous estimates of the megalodon's size were based solely on its teeth compared to the star of "Jaws."
- The prehistoric monster is as closely related to other sharks.
- Imagine just a dorsal fin as tall as you are.
<p>For anyone already terrified by ferocious sharks — few of them actually are, of course — the prehistoric <a href="https://www.livescience.com/63361-megalodon-facts.html" target="_blank">megalodon</a>, <em>Otodus megalodon</em>, goes several steps beyond a nightmare. Not much is known about the animal that roamed the seas from 23 million to about three million years ago. The most definitive fossils are triangular teeth that are larger than a human hand, really not much from which to extrapolate a complete picture of the shark. Even so, they suggest a gargantuan predator. Have you seen "<a href="https://www.imdb.com/title/tt4779682/" target="_blank">The Meg</a>"?</p><p>Now a new, open-source study from the University of Bristol and Swansea University published in the journal <a href="https://www.nature.com/articles/s41598-020-71387-y" target="_blank">Scientific Reports</a> purports to have figured the megalodon's true dimensions, and they don't disappoint.</p>

Credit: Reconstruction by Oliver E. Demuth/Scientific Reports<p>The study proposes the following approximate measurements for a full-grown megalodon:</p><ul><li>Length: about 16 meters (52.5 feet). A full-size school bus is just 45 feet long</li><li>Head size: about 4.65 meters long (15.3 feet) </li><li>Dorsal fin: about 1.62 meters tall (5.3 feet). A person could stand on the back of a megalodon and be about as tall as the fin.</li><li>Tail fin: about 3.85 meters high (12.6 feet) </li></ul><p>Let's just hope this sucker is really extinct. </p>
