In 2004 Naish and colleagues described a giant Isle of Wight sauropod dinosaur that appears closely related to the North American brachiosaurid "Sauroposeidon", and informally referred to as Angloposeidon. Prior to the 2006 description of "Turiasaurus" from Spain, this was the largest dinosaur reported from Europe. In 2005 he coauthored the description of the new Cretaceous turtle "Araripemys arturi", and in 2006 he and David Martill published a revision of the South American crested pterosaurs "Tupuxuara" and "Thalassodromeus". During 2007 and 2008, Naish and Martill published a major revision of British dinosaurs; Naish also published work with Barbara Sánchez-Hernández and Michael J. Benton on the vertebrate fossils of Galve in Spain. The Galve fossils are significant in including istiodactylid pterosaurs, heterodontosaurids and spinosaurines. In 2007, Naish co-authored the description of the new sauropod "Xenoposeidon" with fellow Portsmouth-based palaeontologist Mike P. Taylor. In 2008 he published an evaluation of azhdarchid pterosaurs with Mark Witton, in which they argued that azhdarchids were stork- or ground hornbill-like generalists, foraging in diverse environments for small animals and carrion. Along with his colleagues Mike Taylor and Matt Wedel he published a paper on sauropod neck posture in 2008. In 2010 Naish published a paper on the theoretical flotation abilities of giraffes. In 2011 Hone, Naish and Cuthill published a paper on mutual selection in dinosaurs and pterosaurs In 2013, Naish described "Vectidraco daisymorrisae", a small azhdarchoid pterosaur from the Isle of Wight. Also in 2013 Naish and Witton published a follow-up to their 2008 paper on terrestrial stalking in azhdarchid pterosaurs. In 2015 Naish and colleagues published on a new, as yet unnamed, Transylvanian pterosaur taxon.
