If you were alive in the forests of the Jurassic period some 165 million years ago, you likely would have heard the below sound – before, of course, your screams filled the air as a hungry Allosaurus hunted you down.
How did scientists achieve this? By analyzing the fossilized wing structure of a long-extinct bushcricket from the period and comparing it to the structures of 59 modern-day katydid species. A computer took all of this information and spit out the result – giving us likely the closest audio hint of the Jurassic period we’re likely to ever get.
“The Jurassic forest was already packed with many animals singing at night,” Fernando Montealegre-Zapata, a University of Bristol biologist told MSNBC. “I’m not just talking about the crickets but the frogs. That would create a noisy environment, and in a noisy environment the best way to communicate is with a single frequency, and loudly.”
