Unenlagiid theropods: are they members of the Dromaeosauridae (Theropoda, Maniraptora)?
In the present paper we analyze the phylogenetic position of the derived Gondwanan theropod clade Unenlagiidae. Although this group has been frequently considered as deeply nested within Deinonychosauria and Dromaeosauridae, most of the features supporting this interpretation are conflictive, at lea...

| description | In the present paper we analyze the phylogenetic position of the derived Gondwanan theropod clade Unenlagiidae. Although this group has been frequently considered as deeply nested within Deinonychosauria and Dromaeosauridae, most of the features supporting this interpretation are conflictive, at least. Modification of integrative databases, such as that recently published by Hu et al. (2009), produces significant changes in the topological distribution of taxa within Deinonychosauria, depicting unenlagiids outside this clade. Our analysis retrieves, in contrast, a monophyletic Avialae formed by Unenlagiidae plus Aves.<br>No presente trabalho analisou-se a posição filogenética do clado derivado de terópodas gondwânicos Unenlagiidae. Embora este grupo tenha sido frequentemente considerado como profundamente enraizado entre Deinonychosauria e Dromaeosauridae, grande parte das características que sustentam esta interpretação e no minimo conflitiva. A modificação de bancos de dados integrativos, tal como a recentemente publicada por Hu et al. (2009), produz mudanças significativas na distribuifao topologica dos táxons dentro de Deinonychosauria, representando unenlagiids fora deste clado. Nossa analise recupera, em contrapartida, um Avialae monofilético formado por Unenlagiidae e Aves. |
