Evolutionary History of Microsyopoidea (Mammalia, ?Primates) and the Relationship between Plesiadapiforms and Primates

Pp. vii, (1), 157; 58 text-figures (fine line-drawings of skulls, jaws and teeth, maps, geological time diagrams, phylogenies, and bivariate plots).  Original gray pictorial stiff wrappers, lettered in white on the spine and front cover, 4to.  University of Michigan Papers on Paleontology no. 27.  This major monograph provides evidence the Plesiadapiforms are not related to euprimates (primates of modern aspect).  Plesiadapiforms are actually more closely related to the fossil “dermopterans” (Plagiomenidae) than either is to euprimates.  The work also concludes that the Microsyopoidea are more closely related to Plesiadapiforms than they are to euprimates.  Thus, the Microsyopoidea are not considered a member of the primate order.  No ownership marks and no signs of use.  Inscribed by the author on the title page.
