animals. Isolated teeth and bones from the Isle of Wight, including hand bones reported in 1998 and a vertebra reported by the British palaeontologists Steve Hutt and Penny Newbery in 2004, have been attributed to this genus. A maxilla fragment from La Rioja, Spain, was attributed to Baryonyx by the Spanish palaeontologists Luis I. Viera and José Angel Torres in 1995 (although the American palaeontologist Thomas R. Holtz and colleagues raised the possibility that it could have belonged to Suchomimus in 2004). In 1999, a postorbital, , tooth, vertebral remains, (hand bones), and a phalanx from the Salas de los Infantes deposit in Burgos Province, Spain, were attributed to an immature Baryonyx (though some of these elements are unknown in the holotype) by the Spanish palaeontologist Carolina Fuentes Vidarte and colleagues. Dinosaur tracks near Burgos have also been suggested to belong to Baryonyx or a similar theropod. In 2011, a specimen (Catalogued as ML1190 in Museu da Lourinhã) from the Papo Seco Formation in Boca do Chapim, Portugal, with a fragmentary dentary, teeth, vertebrae, ribs, hip bones, a scapula, and a phalanx bone, was attributed to Baryonyx by the Portuguese palaeontologist Octávio Mateus and colleagues, the most complete Iberian remains of the animal. The skeletal elements of this specimen are also represented in the more complete holotype (which was of similar size), except for the mid-neck vertebrae. In 2018, the British palaeontologist Thomas M. S. Arden and colleagues found that the Portuguese skeleton did not belong to Baryonyx, since the front of its dentary bone was not strongly upturned. This specimen was made the basis of the new genus Iberospinus by Mateus and Darío Estraviz-López in 2022. Some additional spinosaurid remains from Iberia may belong to taxa other than Baryonyx, including Vallibonavenatrix from Morella. In 2021, the British palaeontologist Chris T. Barker and colleagues described two new spinosaurid genera from the Wessex Formation of the Isle of Wight, Ceratosuchops and Riparovenator (the latter named R. milnerae honouring Milner for her contributions to spinosaurid research), and stated that spinosaurid material from there that had previously been attributed to the contemporary Baryonyx could have belonged to other taxa instead. These specimens had previously been assigned to Baryonyx in a 2017 conference abstract. Barker and colleagues stated that the recognition of the Wessex Formation specimens as new genera renders the presence of Baryonyx there ambiguous, and most of the previously assigned isolated material
