New Study Uncovers Megalodon’s Massive Size: Could They Reach 80 Feet Long?
Megalodons, the ancient ocean predators that once roamed the seas, have long been depicted as oversized great white sharks. However, groundbreaking research suggests that these massive creatures may have been even larger and more slender than previously imagined.
Phillip Sternes, an educator at SeaWorld San Diego and co-author of the study, revealed that previous estimates based on teeth suggested megalodons could reach lengths of about 18-20 meters (59-65 feet). However, new findings indicate that these formidable sharks could have grown up to a staggering 80 feet (24.3 meters) in length, surpassing earlier predictions by 15 feet (4.5 meters).
The study, published in the journal Palaeontologia Electronica, delved into the world of megalodons, creatures that reigned over ancient Earth between 20 million and 3.6 million years ago. Despite the absence of complete megalodon skeletons, researchers pieced together information from fossils of vertebrae, scales, and teeth to reconstruct the image of these prehistoric giants.
Unraveling the Mysteries of Megalodon Size
The core of the study involved a meticulous analysis of megalodon fossils, comparing them with a diverse array of 145 living and 20 extinct shark species. By scrutinizing the proportions of the megalodon’s trunk in relation to other sharks, researchers arrived at a more accurate estimation of its size.
Based on the discovery of a 36-foot-long section of megalodon spine, the team calculated that the shark likely possessed a 6-foot-long head and a 12-foot-long tail, leading to a total length of 54 feet (16.4 meters). However, the existence of a vertebra measuring up to 9 inches in diameter hinted at the possibility of megalodons reaching a colossal 80 feet in length.
Moreover, the study unearthed intriguing insights into megalodon reproduction, suggesting that these mighty creatures gave birth to live young measuring 12 to 13 feet in length.
Shaping the Megalodon’s Form
In addition to revising estimates of megalodon size, researchers also shed light on the creature’s shape. While previous assumptions likened megalodons to giant great white sharks, the study’s lead author, Kenshu Shimada of DePaul University, proposed a different perspective.
Contrary to popular belief, the megalodon likely boasted a more slender and streamlined physique, akin to a lemon shark rather than the stocky build of a great white. Drawing parallels to the hydrodynamic movements of whale sharks and basking sharks, the researchers painted a new picture of the megalodon’s appearance.
However, Jack Cooper, a megalodon expert at Swansea University, remains cautious about embracing this revised concept entirely. He underscores the need for further evidence before definitively confirming the megalodon’s body shape.
As the quest for understanding these ancient behemoths continues, each revelation brings us closer to unraveling the mysteries of the megalodon’s existence and appearance.
