masracetus

Masracetus (from Arabic Masr, "Egypt", and Greek ketos, "whale")[1] is an extinct genus of basilosaurid ancient whale known from the Late Eocene (Priabonian, 37.2 to 33.9 million years ago) of Egypt.[2]

Masracetus was briefly described in an addendum by Gingerich 2007 and is known from just an assemblage of vertebrae and a poorly reconstructed skull from 1908. The lumbar vertebrae are large but relatively short (anteroposteriorly) compared to those of other archaeocetes; the diameter is almost the same as for Basilosaurus isis but the length is less than half of the latter. Masracetus is larger than Cynthiacetus,[3] but it is suggested that the former might be synonymized as a junior synonym with the latter.[4]

The species name honours Richard Markgraf, palaeontologist Ernst Stromer's fossil collector, who collected the type specimen in 1905.[1]

Masracetus' type locality is the Birket Qarun Formation in Dimê (29.5°N 30.7°E, paleocoordinates 24.9°N 26.6°E) north of lake Birket Qarun,[5] but specimens have also been found in the Qattara Depression and Fayum.[6][7][8][9]
