Aggiosaurus

Aggiosaurus is an extinct genus of geosaurine metriorhynchid crocodyliform known from the Late Jurassic (late Oxfordian stage) of Nice, southeastern France. It contains a single species, Aggiosaurus nicaeensis, which was named by H. Ambayrac in 1913.
History of discovery.
"Aggiosaurus" is known only from its holotype, an unnumbered, poorly preserved upper jaw collected by H. Ambayrac in 1912, preserved in limestone which is now housed in the Muséum d'histoire naturelle de Nice. It was collected from the late Oxfordian-aged locality of Cap d’Aggio-La Turbie, in Nice, France. It was initially described as a megalosaurid dinosaur by Ambayrac (1913). Later, Buffetaut (1982) demonstrated that it was in fact a metriorhynchid, closely related to, if not a member of "Dakosaurus". As the type specimen is poorly preserved it is sometimes considered to be a nomen dubium. Young & Andrade (2009) suggested that "Aggiosaurus" is a junior synonym of "Dakosaurus", and that "A. nicaeensis" is referrable to "Dakosaurus" as a distinct species provisionally. They based this referral on its unusually large dentition (apicobasal length in excess of ) that thought to be unique to species of "Dakosaurus" among all other thalattosuchians. "Aggiosaurus" actually has the largest dentition of any known metriorhynchid (up to in apicobasal length), although further phylogenetic analyses found that large robust teeth present also in other geosaurins, such as "Torvoneustes". Young "et al." (2012) resurrected the genus name "Plesiosuchus" for "D. manselii" (which also present this trait) as their phylogenetic analysis found a paraphyletic "Dakosaurus" and suggested more basal position for it within Geosaurini than previously thought. As the presence of unusually large dentition (apicobasal length in excess of ) was considered to be homoplastic among geosaurins, "Aggiosaurus" cannot be considered a junior synonym of either "Dakosaurus" or "Plesiosuchus".
Etymology.
"Aggiosaurus" was first described and named by H. Ambayrac in 1913, and the type species is "Aggiosaurus nicaeensis". The generic name is derived from the name of its type locality, Cap d'Aggio-La Turbie, and from "" (), meaning "lizard" in Ancient Greek. The specific name honors Nice, France, in which it was discovered.
