exciting find, the genus name of this whale
is a reference to the
golden colouration of the bones of the type specimen. It is important
to note that should further fossilised bones of this genus be
discovered they might not have the same colouration since the colour of
holotype bones was due to the mineral content of the rocks that they
were preserved in.
Chrysocetus has been identified as a basilosaurid whale, a group of oceanic predatory whales that include genera such as Zygorhiza, Dorudon, Ancalecetus, and of course the type genus and most famous of all of these, Basilosaurus. Individual Chrysocetus would of course also have been expected to be apex predators that targeted everything from fish to other marine mammals.
