is a genus of mosasaur
that lived in waters around North Africa during
the latest Cretaceous. Gavialimimus is noted for
its jaws which are
substantially longer and more slender than those of most other
mosasaurs. This would clearly be an adaptation for specialised
feeding, possibly for either fish or squid. This may have also been
a case of a mosasaur adapting to fill an ecological niche left behind
by some of the specialised ichthyosaurs
that had long been extinct for
tens of millions of years before Gavialimimus
