The present study reconsiders the taxonomic placement of this interesting specimen, given the significant advances in understanding of the Troodontidae that have taken place since it was first described. Morphological comparisons and numerical phylogentic analyses indicate that V 10597 differs significantly from other troodontids, including L. tani, in numerous hindlimb features and particularly in the proportions of various hindlimb elements. These differences are likely to be taxonomic, and suggest that V 10597 represents a new troodontid. Furthermore, histological analysis indicates that V 10597 is unlikely to be a juvenile of L. tani or any other large troodontid. Based on the available morphological and histological information, we propose the erection of a new taxon, Philovenator gen. et sp. nov., based on V 10597. This new find increases the known taxonomic diversity and morphological disparity of Late Cretaceous troodontids.} }
