Furry Folk: Synapsids and Mammals
FURRY FOLK: SYNAPSIDS AND MAMMALS Of all the great transitions between major structural grades within vertebrates, the transition from basal amniotes to basal mammals is represented by the most complete and continuous fossil record, extending from the Middle Pennsylvanian to the Late Triassic and spanning some 75 to 100 million years. —James Hopson, “Synapsid evolution and the radiation of non-eutherian mammals,” 1994 At the very beginning of their history, amniotes split into two lineages, the synapsids and the reptiles. Traditionally, the earliest synapsids have been called the “mammal-like reptiles,” but this is a misnomer. The earliest synapsids had nothing to do with reptiles as the term is normally used (referring to the living reptiles and their extinct relatives). Early synapsids are “reptilian” only in the sense that they initially retained a lot of primitive amniote characters. Part of the reason for the persistence of this archaic usage is the precladistic view that the synapsids are descended from “anapsid” reptiles, so they are also reptiles. In fact, a lot of the “anapsids” of the Carboniferous, such as Hylonomus, which once had been postulated as ancestral to synapsids, are actually derived members of the diapsids (Gauthier, 1994). Furthermore, the earliest reptiles (Westlothiana from the Early Carboniferous) and the earliest synapsids (Protoclepsydrops from the Early Carboniferous and Archaeothyris from the Middle Carboniferous) are equally ancient, showing that their lineages diverged at the beginning of the Carboniferous, rather than synapsids evolving from the “anapsids.” For all these reasons, it is no longer appropriate to use the term “mammal-like reptiles.” If one must use a nontaxonomic term, “protomammals” is a alternative with no misleading phylogenetic implications. -

John Flynn, Secretary, gave his report, which included the following motions: motion to accept 1993 annual meeting minutes; motion to accept 1994 midyear meeting minutes; motion to accept the Secretary's report. All motions were seconded and approved by vote of attending SVP members. Flynn also reviewed the 1993 94 election ballot results noting that Louis Jacobs will serve as Vice President, John R. Bolt as Treasurer, and Lawrence Flynn as the Member-at-Large in 1994 95. John R. Bolt, Treasurer, presented his report which included an overview of the Society's financial position as well as a review of the 1994 95 budget. A motion to accept the Treasurer's report was made, seconded, and approved.

HISTORY OF EARLY CENOZOIC VERTEBRATE PALEONTOLOGY IN THE BIGHORN BASIN Philip D. Gingerich Abstract.- The first fossil mammals from the Bighorn Basin were found by Wortman and described by Cope in 1880. These are early Wasatchian in age, and probably came from the southern part of the basin. During Wortman's 1881 expedition he collected mammalian faunas of both middle and late Wasatchian age in the central Bighorn Basin. The Clarkforkian fauna was first documented by Sinclair and Granger in 191 1 and 1912 in the northern Bighorn and Clark's Fork basins. Sinclair and Jepsen found Puercan, Torrejonian, and Tiffanian faunas on the flanks of Polecat Bench in 1929. Knowledge of these Paleocene and early Eocene land mammal ages has been augmented considerably during the past fifty years, and recently middle Eocene and Oligocene faunas have been discovered on the margins of the Bighorn Basin as well. Unpublished field records complement published information in illuminating the life and times of paleontologists working in the Bighorn Basin during the past century. INTRODUCTION carefully retracing the steps of earlier collectors it is possible to duplicate their collections and determine, One hundred years of paleontological research on in some cases exactly, the stratigraphic level from early Cenozoic faunas in the Bighorn Basin have which important type and referred specimens were yielded the most complete record of mammalian collected. The purpose of this chapter is to outline the evolution through the Paleocene and early Eocene history of paleontological collecting in the Bighorn known anywhere in the world. In recent years a few Basin, with particular attention to the modern bio- scattered middle Eocene and Oligocene fossil local- stratigrahic context of important early collections. -
Snout and Orbit of Cretaceous Asian Multitiuberculates Studied by Serial Sections
Snout and orbit of Cretaceous Asian multitiuberculates studied by serial sections J0RN H. HURUM Hurum, J.H. 1994. Snout and orbit of Cretaceous Asian multitiuberculates studied by serial sections. Acta Palaeontologica Polonica 39, 2, 181-221. The orbital wall in Nemegtbaatar gohiensis and Chulsanbaatar vulgaris, from the Late Crrtaceous of the Gobi Desert, Mongolia, comprises a small lacrimal ante- riorly, large orbital process of the frontal dorsally, orbitosphenoid posteriorly and maxilla ventrally. Nemegtbaatar also posesses an orbital process of the palatine ventrally, not recognized in Chulsanbaatar. Large frontal sinuses of both taxa are interpreted as related to lack of the sagittal crest. Other anatomical characters found in this study, such as orbital process of the frontal, ossified turbinals, ossified ethmoid and vomer, frontal, sphenoidal and maxillary sinuses, and the presence of the orbital process of palatine in Nemegtbaatar suggest a close relationship of multituberculates to monotremes and therian mammals. By the new data obtained from the serial sections the diagnostic character: orbital process of the palatine absent in Multituberculata, is no longer valid. Ossified ethmoid and maxillary turbinals, characteristic for Monotremata, Vincekstes, Marsupialia and Placentalia, are also present in Multituberculata. The precence of a cribiform plate and the precence of an ossified plate of ethmoid in Multituber- c~datais shared with Monotremata, Vincelestes, Marsupialia and Placentalia.

Introduction More than half a century ago George Gaylord Simpson stated (1926: p. 228) that the order Multituberculata: 'includes members of the very oldest known mammalian faunas and it subsisted practically Irom the beginning of reptilian dominance on into that of mammalian ascendency.
