Kellner Multidisciplinaria (Ciencias Naturales y Exactas) Argentina Pterosauria Lower Cretaceous Río Belgrano Formation Pterosaur remains from the Río Belgrano Formation, Santa Cruz Province, Argentina, were found close tothe Estancia Río Roble, along with several ammonoids that indicate a Barremian age for those strata. Thespecimens (MACN-SC 3617) consist of one ulna and one element tentatively identified as a portion of a wingmetacarpal. The ulna shows morphological affinities with the Pteranodontoidea (sensu Kellner 1996), particularlywith the members of the Anhangueridae by having a well developed ventral crest close to the proximalarticulation, and is tentatively referred to this pterosaur clade. The oldest record of the Anhangueridae,previously limited to the Aptian/Albian, is therefore extended to the Barremian. The Argentinean material ispreserved in three dimensions, an unusual condition for pterosaur fossils from that country, indicating thatthe site situated near the Estancia Río Roble has a great potential for new and well preserved specimens. 2003 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32775407 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.75 |
