Gilchristosuchus

Name: Gilchristosuchus ‭(‬Gilchrist crocodile‭)‬.
Phonetic: Gil-cry-st-soo-kus.
Named By: X.‭ ‬C.‭ ‬Wu‭ & ‬D.‭ ‬B.‭ ‬Brinkman‭ ‬-‭ ‬1993.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Crocodylomorpha,‭ ‬Eusuchia‭?
Species: G.‭ ‬palatinus‭ (‬type‭)‬.
Diet: Carnivore/Piscivore.
Size: Uncertain,‭ ‬but skull is estimated to have been around‭ ‬15‭ ‬centimetres long when complete.
Known locations: Canada,‭ ‬Alberta‭ ‬-‭ ‬Milk River Formation.
Time period: Santonian of the Cretaceous.
Fossil representation: Partial remains of the posterior‭ (‬rear‭) ‬portion of the skull and a cervical‭ (‬neck‭) ‬vertebra.

       Living in the late Cretaceous,‭ ‬Gilchristosuchus was a crocodile that in evolutionary terms‭ ‬may have come close to modern crocodiles,‭ ‬yet may not have actually been one of them.‭ ‬The size of Gilchristosuchus is still unknown but the one partial skull known shows signs of fusing,‭ ‬indicating that it was an adult specimen.‭ ‬With the skull estimated at fifteen centimetres,‭ ‬Gilchristosuchus would have only have been a very small croc.‭ ‬Although so far only a single vertebra and partial skull have been assigned to Gilchristosuchus,‭ ‬some fossils assigned to the genera Brachychampsa and Leidyosuchus are believed to possibly belong to Gilchristosuchus.
       The holotype specimen of Gilchristosuchus was discovered in the‭ ‬Milk‭ ‬River Formation of Alberta,‭ ‬Canada.‭ ‬With this in mind,‭ ‬Gilchristosuchus would have likely shared its habitat with dinosaurs such as early pachycephalosaurs like Acrotholus,‭ ‬as well as small predatory dinosaurs like Saurornitholestes and Richardoestesia,‭ ‬which may have actually been a threat to little crocs like Gilchristosuchus.
