Dimorphodon weintraubi

"Dimorphodon" weintraubi is an extinct species of pterosaur originally thought to be a species of the primitive pterosaur genus Dimorphodon from the Early Jurassic of Mexico. It was named by James Clark and others in 1998, in honour of Dr. Robert L. Weintraub. Phylogenetic analyses have found "Dimorphodon" weintraubi as the earliest-diverging anurognathid, extending the origin of this clade to the Early Jurassic.
