Parviraptor Evans, 1994a

(figs. 54B, 55B, 56A)

DIAGNOSIS: Parviraptor estesi and P. cf. estesi are joined in this analysis by two unambiguous synapomorphies. These are 83(2) presence of an expansive nuchal fossa that extends well onto the parietal table and 214(2) ‘‘modified pleurodont’’ dentition (sensu Zaher and Rieppel, 1999a).

COMMENTS: I refrain from defining the clade Parviraptor as constituted here, preferring to leave that to the original describer of the specimens included in it. Parviraptor estesi and P. cf. estesi , as described by Evans (1994a), are each represented by incomplete remains that may be diagnosed from one another and probably separated by several million years ( Evans, 1994a). However, the present analysis supports Evans’ (1994a) suggestion that these two taxa form a clade.
