Thalassodromidae (meaning "sea runners") is a family of pterodactyloid pterosaurs from the early Cretaceous period of Brazil. It contains two genera, ''Thalassodromeus'' and ''Tupuxuara''. ==Classification== The classification of thalassodromids is controversial. Some studies, including one by Lü and colleagues in 2008, have found that the thalassodromids are more closely related to the azhdarchids than to the tapejarids,〔Lü, J., Unwin, D.M., Xu, L., and Zhang, X. (2008). "A new azhdarchoid pterosaur from the Lower Cretaceous of China and its implications for pterosaur phylogeny and evolution." ''Naturwissenschaften'',〕 and have placed them in their own family (which has sometimes been referred to as Tupuxuaridae,〔Martill, D.M., Bechly, G., and Heads, S.W. (2007). "Appendix: species list for the Crato Formation." In: Martill, D.M., Bechly, G., and Loveridge, R.F. (eds.), 2007. ''The Crato Fossil Beds of Brazil: Window into an Ancient World.'' Cambridge University Press, Cambridge. Pp. 582–607.〕 though Thalassodrominae was named first〔). Alternately, they have been considered a subfamily (Thalassodrominae) within the Tapejaridae.〔Pinheiro, F.L., Fortier, D.C., Schultz, C.L., De Andrade, J.A.F.G. and Bantim, R.A.M. (in press). "New information on ''Tupandactylus imperator'', with comments on the relationships of Tapejaridae (Pterosauria)." ''Acta Palaeontologica Polonica'', in press, available online 03 Jan 2011. 〕 Below are three alternate cladograms resulting from studies of azhdarchoid relationships. The first, presented by Felipe Pinheiro and colleagues in 2011, found the thalassodromids as subgroup within the Tapejaridae. The second, presented by Lu and colleagues in 2008, found them to be closer to the Azhdarchidae. The third, presented by Andres, Clark & Xu, 2014, also found thalassodromids closer to azhdarchids and as the sister group of the dsungaripterids. }} }} }} }} }} }} 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thalassodromidae」の詳細全文を読む スポンサード リンク
