Togocetus (“Togo whale”) is a genus of extinct cetacean from the Lutetian (lower Eocene) of Togo, known from a fossilized skeleton discovered few kilometers north-east of Lomé.

Discovery and description

The skeleton was found in a phosphate mining area, Kpogamé-Hahotoé, which is located just north of Lake Togo. It was embedded in a phospharenite bonebed dating back to 46 – 44 million years ago, and overlying an older rock unit, the Tabligbo Group. The remains were described in 2014 by Philip D. Gingerich and Henri Cappetta, who established for it the new monotypic genus Togocetus and the new species T. traversei, dedicated to Michel Traverse.

According to the two authors, Togocetus was a semiaquatic animal which must have weighed around 300–400 kilograms (660–880 lb). It was a protocetid with rather primitive traits such as a still quite long neck, a digitigrade manus and a swim-specialized pes. It shared many similarities with the protocetid genera Protocetus and Pappocetus, the main differences being a smaller mandibular canal, the loss of the fovea capitis femoris (hence of the ligament of head of femur) and some traits related to the molar trigonids.
