A, proximal view; B, lateral; C, medial; D, distal, x OTHER MATERIAL REFERRED TO THE SAME FAMILY Taquet (1984) described two fragments from the EIrhaz Formation (Aptian) of Gadoufaoua, Niger, as mandibular symphyses of a spinosaurid (Musee National d'Histoire Naturelle, Paris, MNHN GDF 365 and 366); they were refigured more clearly in Kellner & Campos 1996 (fig. 7). Each is virtually identical to the conjoined premaxillae of the holotype of Baryonyx (Charig & Milner 1986: 1990: 139) except in that they possess seven alveoli on each side, not six on the left and seven on the right as in R9951. We consider that these snouts, despite their much younger age, are referable to Baryonyx sp. indet. More recently, Viera & Torres (1995: figs 1-2) referred a left maxilla fragment (Museo de San Telmo, San Sebastian, GA-2065) from the Enciso Group, Barremian of Igea, La Rioja, Spain, to Baryonyx walkeri. It is less complete and about 75% of the size of the holotype maxilla but otherwise indistinguishable. The tip, ante- rior to the 3rd alveolus is missing but complete 8th, 9th and partial 10th alveoli are present confirming that the pattern of evenly spaced subcircular alveoli, gradually decreasing in size, continues further posteriorly than is preserved on the holotype maxilla. The following isolated tooth crowns are referred to cf. Baryonyx; their fragmentary nature and the consequent lack of further informa- tion precludes a more precise identificafion. Wessex Formation (=Wealden Shales, Barremian), Isle of Wight (Isle ofWight County , Sandown IWCMS 3642 and 5120from Hanover Point; IWCMS 5122, IWCMS 1995 207-209, University of Portsmouth, , all unlocalised) described as possible baryonychid by Martill & Hutt (1996). All these crowns are virtually identical with the teeth of the holotype
