Abstract

Here we report a new oviraptorid taxon based on a specimen possibly collected from the Upper Cretaceous Nanxiong Formation of Ganzhou, Jiangxi, China. This new taxon is distinguishable from other species based on the following features: a crest formed by the premaxillae and nasals having a step wise posterior end and bearing two longitudinal grooves and numerous oblique striations on each of its lateral surfaces, an extremely elongate external naris that is posteriorly situated and close to the or bit, a deep fossa on the dorsal surface of the palatal ramus of the pterygoid, several longitudinal grooves along the posterior part of the dorsal margin of the dentary, and several tubercles along the lateral shelf at the dorsal margin of the surangular. This new taxon possesses some palatal and mandibular features not seen in other oviraptorids but similar to those in more basal oviraptorosaurs, suggesting a relatively basal position for this taxon within the Oviraptoridae. This systematic hypothesis is supported by a numerical cladistic analysis. This discovery not only adds to the known diversity of Late Cretaceous

Holotype

IVPP V 16896, a nearly complete skull and mandible

Type locality and horizon: The specimen was acquired from an amateur collector who is not willing to reveal his indentity. The only information concerning the provenance of the specimen provided by this collector is that the specimen was collected in the Hongcheng Basin near Ganzhou City, Jiangxi Province. The red beds exposed in the Hongcheng Basin are normally correlated with the Upper Cretaceous Nanxiong Formation (Sato, et al., 2005)

Etymology

Genus name from \\\\\\\"ban\\\\\\\", speckle, but sometimes referring to stripes in Chinese, and \\\\\\\"ji\\\\\\\", crest; refers to the animal\\\\\\\'s bearing a crest with distinctive striations over the snout. The species name \\\\\\\"long\\\\\\\" is a tranliteration of the Chinese word for dragon.

Diagnosis

An oviraptorid distinguishable from other species based on the following features: a crest formed by the premaxillae and nasals having a step-wise posterior end and bearing two longitudinal grooves ans numerous oblique striations on each of its lateral surfaces, an extremely enlongate naris that is posteriorly situated and close to the orbit, a deep fossa on the dorsal surface of the palatal ramus of the pterygoid, several longitudinal grooves alang the posterior part of the dorsal margin of the dentary, and several turbercles along the lateral shelf at the dorsal margin of the surangular
