Scientists Challenge Popular Image of Megalodon as a Gigantic Shark

The popular image of the megalodon as a massive, beefy shark may be incorrect, according to a new study. Published in the journal Palaeontologia Electronica, the study suggests that the megalodon, an extinct apex predator, may have been slimmer and longer than previously thought.

The megalodon, which went extinct about 3.6 million years ago, is often depicted as a supersized great white shark, with a powerful body spanning 50 feet from nose to tail. However, the new research challenges this perception and proposes that the megalodon resembled a mako shark, with an elongated and slender body.

The debate about the appearance of the megalodon has been ongoing among scientists, as its cartilage skeleton does not fossilize well. While fossilized segments of its backbone have been discovered, they do not provide a complete picture of its body structure. Scientists have relied on analogies to living macropredators, such as the great white shark, to speculate about the megalodon’s appearance.

This new study argues against the previous hypothesis that the megalodon had a robust and bulky body. Instead, the researchers suggest that the slender body shape indicates that the megalodon may have been a slow cruiser, unlike the powerful swimmers of modern great white sharks.

Both this study and the previous one have received critiques from outside experts, highlighting the ongoing nature of scientific inquiry. Despite the differences in interpretation, both studies agree that the megalodon was likely longer than previously thought.

The fascination with the megalodon among scientists and the general public remains strong. As Dana Ehret, a curator of natural history, pointed out, imagining a shark even 20 feet longer than the biggest shark today is mind-boggling. The megalodon’s true appearance may still remain a mystery, but the ongoing discussions and research shed new light on this ancient mega-predator.

FAQ

Q: What does the new study suggest about the appearance of the megalodon?
A: The new study suggests that the megalodon may have been slimmer and longer than previously thought, resembling a mako shark rather than a supersized great white shark.

Q: Why has the appearance of the megalodon been a subject of debate?
A: The megalodon’s cartilage skeleton does not fossilize well, making it difficult to determine its true appearance. Scientists have relied on analogies to living macropredators, such as the great white shark, to speculate about its appearance.

Q: What does the new study argue against?
A: The new study argues against the previous hypothesis that the megalodon had a robust and bulky body. Instead, it suggests that the megalodon had a slender body shape and may have been a slower swimmer compared to modern great white sharks.

Q: What do both studies agree on?
A: Despite the differences in interpretation, both studies agree that the megalodon was likely longer than previously thought.

Q: Why is the fascination with the megalodon still strong?
A: The megalodon’s massive size, even larger than the biggest sharks today, continues to captivate scientists and the general public.
