Phylogenetic position of Turanoceratops (Dinosauria: Ceratopsia)

Comments & Replies

Farke et al. (2009) commented on our recent paper describing new material of the Late Cretaceous ceratopsian dinosaur Turanoceratops from Uzbekistan (Sues and Averianov 2009). We provided evidence that Turanoceratops is the first member of the clade Ceratopsidae known outside North America. Farke et al. (2009) coded Turanoceratops using a character-taxon matrix for Ceratopsidae by Dodson et al. (2004) and found its phylogenetic position as a sister-taxon to Ceratopsidae rather than as a member of that clade. Their coding is as follows: 21(1), 22(0), 25(0), 29(0), 57(0), 60(1), 61(1) and 62(0). Our coding of Turanoceratops, based on direct observation of the specimens, is 21(1), 22(0), 23(0), 25(0), 29(1), 30(1), 57(0), 60(1), and 62(1). We specifically disagree on the coding of four characters:

Character 23: postorbital, position of supraorbital ornamentation: centered rostrodorsal or dorsal to orbit (0); centered caudodorsal or caudal to orbit (1). This character was not coded by...
