thumb|left|Life restoration Masracetus was briefly described in an addendum by 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, but it is suggested that the former might be synonymized as a junior synonym with the latter.
