Summary:

- Researchers have provided new estimates on the size of the prehistoric megalodon shark, suggesting it was even larger than previously thought.
- The study, published in the journal Historical Biology, estimates the megalodon could have grown up to 20 meters (66 feet) in length, making it one of the largest predators to have ever existed.
- The findings are based on an analysis of the relationship between the size of megalodon's teeth and the total body length, providing a more accurate estimate of the shark's true size compared to previous methods.
