A critique of some recently proposed paleogene primate taxa and suggested relationships.
The Paleocene mammal from China, Petrolemur brevirostre, is almost certainly not a primate but possibly an early artiodactyl. "Teilhardina americana", described in 1976, is not Teilhardina found in North America but part of the Anemorhysis tenuiculus sample. The genera "Aycrossia" and "Strigorhysis" are the same, single species of Absarokius. The genus "Gazinius" is the same as Anaptomorphus. The cladistics of primate relationships by some authors are based on either embryologically and paleontologically unacceptable dental homologies or assumptions of bizarre character polarities and of numerous parallelisms, unsupported by any evidence.
