About Aegicetus

Aegicetus is an extinct genus of protocetid whale based on a partial skull with much of an associated postcranial skeleton discovered in Egypt. It lived around 35 million years ago (during the Late Eocene), making it the youngest known protocetid to date. Aegicetus was discovered in 2007 at Wadi El Hitan (Gehannam Formation) as a relatively complete skeleton and a partial second specimen. They were assigned to a new genus and species in 2019 by Philip D. Gingerich et al.
