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]
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 (Lua error in package.lua at line 80: module 'strict' not found., paleocoordinates Lua error in package.lua at line 80: module 'strict' not found.) north of lake Birket Qarun,[4] but specimens have also been found in the Qattara Depression and Fayum.[5][6][7][8]
