Led by the incomparable Sanaa El-Sayed, a study out today in Science Advances throws open an important new window on marine fish diversity during the critical few million years following the K-Pg mass extinction. Below: artistic vision of the new fauna by Ian Baylatry.

Comparing the relative volume of the brain endocast, we found that this early whale was quite brainy, which is a surprise, as the first cetaceans with big brains were so far understood to be the fully aquatic basilosaurids.

We ct-scanned the skull of Protocetus atavus, an amphibious cetacean coming from the Mokattam Formation in Egypt. The inner anatomy of the skull was reconstructed, and we were able to reconstruct the brain imprint (endocast) as well as the different components of the nasal cavity.
