If you’ve ever seen a manta ray, you may be able to imagine what the ancient eagle shark looked like in action: a giant, ghostly figure flapping through Cretaceous era seas near present-day Mexico. For the first time, paleontologists describe the new species, discovered in a limestone quarry in northeastern Mexico in 2012, today in Science. Aquilolamna milarcae—a combination of “eagle shark” and the name of the museum that will host the specimen—was a plankton-eater that lived toward the end of the era of the dinosaurs, some 90 million years ago.
