Time period: Maastrichtian of the Cretaceous.
Fossil representation: Partial dentary (lower jaw) and four teeth.
is a genus of abelisaurid
dinosaur that lived in North Africa towards
the end of the Cretaceous period. Chenanisaurus is
named from the
description of a partial lower jaw, and while this does not give us
much to go on, it does reveal a few things. While the jaw is
incomplete, it is that of an abelisaurid dinosaur, and comparable
in size to other large abelisaurid dinosaurs. This jaw alone suggests
that Chenanisaurus grew to at least seven meters
long, maybe more,
though precise details cannot be certain front the jaw alone. The
jaw is also proportionately high to what its complete length would have
been, showing adaptation for a very high bite force. The holotype
bone of Chenanisaurus was found in marine
sediment, showing that this
individual had been swept out to sea.
