Papposaurus
Papposaurus is an extinct genus of proterogyrinid embolomere which lived in the Mississippian (early Carboniferous) of Scotland. It is known from a single species, Papposaurus traquiairi, which is based on an isolated femur discovered in ironstone near Loanhead.[1][2] Though originally compared closely to reptiles,[3] subsequent study has revealed closer similarity to basal embolomeres such as Proterogyrinus and Archeria.[1] With such limited remains, Papposaurus may not be a valid genus. The femur was redescribed in 1986 by T. R. Smithson, who considered Papposaurus traquairi a nomen vanum possibly synonymous with Proterogyrinus scheelei.[4]
