''Broiliellus'' is an extinct genus of dissorophoid temnospondyl within the family Dissorophidae. ''Broiliellus'' is most closely related to the genus ''Dissorophus'', and both have been placed in the subfamily Dissorophinae. ''Broiliellus'' is known from three species from the Early Permian: the type species ''Broiliellus texensis'' and the species ''Broiliellus brevis'' and ''Broiliellus olsoni''. A fourth species, ''Broiliellus novomexicanus'', which was originally named ''Aspidosaurus novomexicanus'', is now thought to fall outside the genus as a member of the subfamily Cacopinae. ==Phylogeny== The phylogenetic analysis of Schoch (2012) found that ''Broiliellus'' was most closely related to ''Dissorophus''. However, the three species of ''Broiliellus'' did not form their own clade, but rather a polytomy (unresolved evolutionary relationship) with ''Dissorophus''.〔 Holmes, Berman & Anderson (2013) named a new species of ''Broiliellus'', ''Broiliellus reiszi''. They performed two phylogenetic analyses using the data matrix of Schoch (2012). In the second analysis the codings for ''"B." novomexicanus'' (i.e. Rio Arriba taxon) were not modified. This analysis yielded more resolved topology and a monophyletic ''Broiliellus'' with the exclusion of ''"B." novomexicanus''. Below is the cladogram from that analysis: }} }} |label2=Dissorophidae |2= }} }} |label3=Cacopinae |3= }} }} }} }} }} }} }} }} }} 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「Broiliellus」の詳細全文を読む スポンサード リンク
