Chicago, Illinois – In a recent study published in the journal Palaeontologia Electronica, Paleobiologist Dr. Kenshu Shimada of DePaul University challenges previous notions about the size and build of the prehistoric shark species Otodus megalodon. His research suggests that megalodon could have reached an impressive length of 80 feet, contrary to the familiar depiction of the massive shark as a bulky predator akin to a great white. Shimada’s findings could prompt a shift in scientists’ understanding of the ancient creature and its evolution.
Megalodon, which existed between 15 million and 3.6 million years ago, dominated the world’s oceans as the apex predator. Despite no complete fossils ever being discovered, scientists have unearthed various megalodon fossils that offer insights into the species. These fossils include large sections of spinal columns, providing valuable information about the shark’s structure and size.
Unlike what was portrayed in the movie “The Meg,” megalodon never coexisted with humans, leading researchers to explore how the immense creature would have looked and moved. By analyzing data from 145 living shark species and 20 extinct species, Shimada and his team developed a new understanding of megalodon’s body plan, suggesting that the massive shark may have had a slender, more streamlined form resembling that of a modern lemon shark. This revelation challenges previous assumptions about megalodon’s appearance and behavior.
Dr. Stephen Godfrey, an expert in paleontology, expressed surprise at Shimada’s proposed similarities between megalodon and lemon sharks, as well as the estimated length of 80 feet for the prehistoric predator. The findings open up discussions among scientists about the relationship between body shape and size in marine vertebrates, shedding light on why some species can grow larger than others with greater efficiency in movement.
While Shimada’s study offers new insights into megalodon’s potential size and appearance, he emphasizes that the discovery of a complete skeleton is crucial to confirm these findings. The search for more fossil evidence continues to unravel mysteries surrounding this ancient shark species and its place in evolutionary history. The study highlights the importance of reevaluating assumptions and embracing new perspectives in scientific research to deepen our understanding of the natural world.
