Talk:Hypselospinus

Confusion of articles?
Didn't the 1888 publication of Lydekker name I. dawsoni, while R. Lydekker, 1889, "Notes on new and other dinosaurian remains", Geological Magazine, decade III, 6(8): 352-356 names I. fittoni?.--MWAK (talk) 06:08, 1 June 2010 (UTC)
 * That is what Norman's new paper indicates, too. The date was changed by J., along with the addition of the specific Lydekker paper, so he may have more insight on this. Firsfron of Ronchester  06:35, 1 June 2010 (UTC)
 * I was taking the dates from the Iguanodon article, but it indeed appears that I got them backward at some point. J. Spencer (talk) 23:52, 1 June 2010 (UTC)

Remains
The specimen referred to Iguanodon cf. fittoni by Maisch (1997) has been assigned to Iguanodontia indet. by Pereda-Suberbiola et. al. (2011). Unlike other Wealden ankylopollexians, it has tall neural spines (characteristic of Ouranosaurus and also found in Hypacrosaurus altispinus). Therefore, the specimen described by Maisch (1997) is a potentially distinct species of Wealden iguanodont.
