A bizarre shark with wing-like fins and a wide, gaping mouth soared through the seas of what is now Mexico about 93 million years ago, when dinosaurs still roamed the Earth, a new study finds.

This odd shark — dubbed Aquilolamna milarcae, or eagle shark of the Milarca Museum, where its fossil will go on display — looks remarkably like manta and devil rays, which also sport finned “wings.” (Rays are closely related to, but are not, sharks.) This shark lived more than 30 million years before either of those creatures existed, the researchers said.
