closeFollow-up paper more precisely identifying fish vertebra as Hiodontiform
Posted by df9465 on 14 Feb 2014 at 18:43 GMT
A follow up paper has been published (Newbrey et al., 2013) that more precisely identifies the fish vertebra found with the Raptorex holotype skeleton (Sereno et al., 2009). Newbrey et al. (2013) present a detailed description of vertebrae from lycopterid fish, and conclude that the Raptorex fish vertebra cannot be assigned to this taxon. Newbrey et al. (2013) find the Raptorex fish vertebra to be indistinguishable from those of hiodontid fish from the Nemegt Formation, Upper Cretaceous, Mongolia, and suggest that Raptorex derives from the Upper Cretaceous. A hiodontiform was one of the possible identifications mooted in (Fowler et al., 2011).

Another recent paper has identified the fish vertebra associated with the R. kriegsteini holotype specimen as belonging to a new genus and species of osteoglossiform fish known only from the Nemegt Formation, Mongolia. The authors specifically note that this supports R. kriegsteini as having derived from the Nemegt Formation (as suggested in Fowler et al., 2011; and Newbrey et al., 2013).
