also expressed strong interest for a meeting on mammal evolution with a general focus similar to that of the rodent gathering. In 1988, Szalay and Luckett, after having planned in detail a program, direc- tion, and core list of participants, were awarded a $30,000 grant by the Alfred P.

Introduction, of the Mammalia, including the extinct taxa. The chapters in these two volumes present a state of phylogenetic affairs of the most critical features studied in mammalian phylogenetics, of the higher groupings themselves, as well as the critical issues of both conceptual and empirical methodologies.

Cranial Morphology and Multituberculate Relationships,ajority of multituberculate cranial features are merely mammalian plesiomorphies. A few specializations do exist and appear to be either peculiar to all multituberculates or evolved within the group. These include inflated vestibular apparatus in taeniolabidoids, reduced postorbital process and juga

Ontogenetic Evidence for Cranial Homologies in Monotremes and Therians, with Special Reference to ,therian mammals. Recent monotremes retain a number of synapsid plesiomorphies in the middle ear. These include the absence of a caput mallei, the synostosis between praearticulare and tympanicum, the columelliform stapes, the presence of a secondary tympanic membrane at the lateral aperture of the r
