Prehistoric megalodon sharks might have been even bigger than previously thought. The chance discovery was made thanks to high schoolers.

What is left are teeth and a few vertebrae, from which they can extrapolate other characteristics.</p><p>Since 2002, a calculation based on the height of megalodon's teeth was commonly used to determine their length.&nbsp;</p><p>But a field trip of high school students from California to the Florida Museum of Natural History brought down that equation.</p><p>The students were told to apply the calculation to replicas of a set of teeth of a single megalodon acquired by the museum.</p><p>Using the calculation, they came up with wildly different estimates for the length of the same shark: from about 40 to 148 feet.&nbsp;</p><p>"I was really surprised," then-PhD student Victor Perez, who led the study and is now an assistant curator of paleontology at the Calvert Marine Museum in Maryland <a href="https://www.eurekalert.org/pub_releases/2021-06/fmon-slg060721.php">said in a press release accompanying the study</a>.

This time, they used the width of the teeth to determine the size of the animal's jaw.&nbsp;</p><p>"I was quite surprised that indeed no one had thought of this before," Leder, now director of the Natural History Museum in Leipzig, Germany, said in a press release.&nbsp;</p><p>The team's method have a range of error, about 10 feet when applied to the largest individuals, Perez said.</p><p>Nevertheless, it shows that megalodon could reach larger sizes than previously thought, Pimiento said.&nbsp;</p><p>The new method has limitations, she said, as it still relies on knowing where the teeth go in the jaw, which could lead to errors.</p><p><a href="https://www.businessinsider.com/megalodon-sharks-bigger-than-thought-after-high-school-trip-2021-6#comments">Join the conversation about this story &#187;</a></p> <p>NOW WATCH: <a href="https://www.businessinsider.com/navy-usns-comfort-hospital-ship-new-york-coronavirus-covid-19-2020-3">How the Navy's largest hospital ship can help with the coronavirus</a></p>
