The correct date of the publication of Ischyrosaurus Cope is 1876, not 1869 [1], making Ischyrosaurus Hulke, 1874 in Lydekker, 1888 unpre-occupied. Cope [2] tried to create Ischyrosaurus for Ischyrotherium on the grounds that Ischyrotherium was a reptile and not a mammal as originally classified by Leidy [3]. However, the name Ischyrosaurus Cope, 1876 is a nomen nudum, on the condition of Cope's attempt, and a junior synonym of Ischyrotherium Leidy, 1856.

The reasoning for the different dates is explained by Spamer et al. (1995- pg. 333). The portion up to page 105 was issued in August, 1869, up to page 235 in April, 1870 and the rest was published in December, 1870. This is on page ii of the index in the volume itself. Since Cope named Ischyrosaurus on pages 38 and 39, the proper year is 1869. -Mickey Mortimer —Preceding unsigned comment added by 67.183.109.183 ( talk) 11:26, 10 January 2011 (UTC)
Hi guys,
Have to say I was a little taken aback to see blogs, the DML and the Paleobiology database being used as references here. Not that I have anything against any of the people who undoubtably known their stuff, but these really aren't suitable references. I've already removed the references made to Darren's blog, and I'm going to move to to the others the now. Just to let you know. Mark t young ( talk) 13:51, 4 August 2008 (UTC)
I went on Google Books to examine Hulke's (1874) paper and there is no mention of the name I. manseli in his work. Therefore, I. manseli was clearly intended for BMNH R41626 without ever being published. The name Ischyrosaurus was never given a diagnosis, and thus Ischyrosaurus and its type species I. manseli are nomina nuda.

Hulke (1874) uses the name Ischyrosaurus three times and refers to his 1869 description of the element before it had been named, which distinguishes it from other taxa. Thus it's not a nomen nudum. -Mickey Mortimer —Preceding unsigned comment added by 67.183.109.183 ( talk) 11:05, 10 January 2011 (UTC)
Barrett et al. (2010) assign Ischyrosaurus to Neosauropoda incertae sedis because the holotype has characters present in both rebbachisaurids and basal titanosauriforms but lacks characters that would permit referral to either group.
