Check for copyvio?[edit]

Could someone check the original source of this for copyright violation? I have an intuition that it may have been copied from either the book it references or from some other website. --Improv 17:41, 17 August 2006 (UTC)

The original text from January does not closely resemble the reference, which can be found online here in html format or here in PDF format. A google search on random bits of text also didn't immediately pull up any copyvio.--Firsfron of Ronchester 19:27, 17 August 2006 (UTC)

Classification[edit]

The article should be updated to reflect that Suuwassea has been recovered as a dicraeosaurid in the analysis of Whitlock (2011). While Woodruff and Fowler (2012) consider Suuwassea a juvenile of a known diplodocid from the Morrison (in part because the degree of bifurcation of its neural spines is ontogenetically variable), Hedrick et al. (in press) disagree with Woodruff and Fowler on the taxonomic status of Suuwassea, even though they do agree that ANS 21122 is a subadult. Additionally, some dicraeosaurid characters of Suuwassea (e.g. posparietal foramen) are also found in the diplodocine Kaatedocus Tschopp and Mateus 2013 and the non-neosauropod Spinophorosaurus (Knoll et. al. 2012). Therefore, Suuwassea remains a dicraeosaurid even if the postparietal foramen is not restricted to Dicraeosauridae.
