Piveteausaurus divesensis

Reptilia - Megalosauridae

Taxonomy
Eustreptospondylus divesensis was named by Walker (1964). Its type specimen is MNHN 1920-7, a partial skull (braincase), and it is a 3D body fossil. Its type locality is Vaches Noires, near Dives, which is in a Callovian marine marl in the Marnes de Dives Formation of France. It is the type species of Piveteausaurus.

It was recombined as Proceratosaurus divesensis by Paul (1988); it was recombined as Piveteausaurus divesensis by Taquet and Welles (1977), Molnar et al. (1990), Buffetaut et al. (1991), Molnar (1991), Currie and Padian (1997), Knoll et al. (1999), Allain (2001), Holtz et al. (2004), Rauhut et al. (2010), Carrano et al. (2012) and Paulina Carabajal and Currie (2012).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
P. Taquet and S. P. Welles 1977Théropode de grandes dimensions avec une table pariétale large et longue; processus paroccipitaux au-dessus du condyle, processus tubéreux larges et modérément longs; foramen magnum trés petit; sphénethmoïde massif; parasphénoïde profond, épais et bas; processus basiptérygoïdiens courts et proches l'un de l'autre.
M. T. Carrano et al. 2012The limited materials of Piveteausaurus are insufficient to determine autapomorphies for this taxon given that the braincase of Leshansaurus is so strikingly similar. However, based on its provenance and morphology the only reasonable candidate for synonymy is Eustreptospondylus, from which it has been specifically distinguished (Walker 1964; see below).
