One of crushing rather than shearing food. those aquatic animals that can be seen on occasion is the river otter. Unlike the beaver, in which the fossil species found at the Monument is almost identical with its modern descendant, the fossil otter at Hagerman and the modern otter found along the Snake River today are different and represent two different groups of otters, one originating in the old world and one in the new.

Ruez Jr. 1,2,3 1 Department of Geological Sciences, The University of Texas at Austin, Austin, TX 78712, USA 2 Current affiliations: Department of Environmental Studies, University of Illinois at Springfield, Springfield, IL 62703, USA; [email protected]; Tel.: +1-217-206-8425 3 Research and Collections Center, Illinois State Museum, Springfield, IL 62703, USA Academic Editor: Olaf Lenz Received: 2 January 2016; Accepted: 26 February 2016; Published: 4 March 2016 Abstract: At least 17 carnivoran taxa occur in the Pliocene Glenns Ferry Formation at Hagerman Fossil Beds National Monument (HAFO), Idaho. This assemblage was examined for stratigraphic changes in species distribution, specimen abundance, and species diversity. Three relatively common mustelids, Trigonictis cookii, Trigonictis macrodon, and Mustela rexroadensis, occur at most stratigraphic levels, but are absent during an interval coinciding with the coolest time segment at HAFO. It is within this gap that two less-common mustelids, Ferinestrix vorax and Buisnictis breviramus, first appear at HAFO; they persist up-section with the more common mustelids listed above. Specimens of Borophagus hilli are restricted to the warm intervals at HAFO, irrespective of the relative abundance of surface water. The other canid at HAFO, Canis lepophagus, is more abundant during the dry intervals at HAFO, regardless of the estimated paleotemperature. Most remarkable is the recovery of many taxa impacted by abrupt climate change, although a notable change is the much higher relative abundance of carnivoran species following a return to warm temperatures.

Meike Köhler Abstract Hipparionins are a clade of tridactyl equids that greatly diversified during the late Miocene throughout the circum-Mediterranean area, with some taxa undergoing dwarfing. Due to their abundance, they have been the subject of several paleoecological studies and constitute a key mammalian group for exploring evolutionary patterns, although more research is necessary to better understand their ecology.

  • Additions and Comments on the Fossil Birds of Agate Fossil Beds National Monument, Sioux County, Nebraska
    ADDITIONS AND COMMENTS ON THE FOSSIL BIRDS OF AGATE FOSSIL BEDS NATIONAL MONUMENT, SIOUX COUNTY, NEBRASKA ROBERT M. CHANDLER Department of Biological and Environmental Sciences Georgia College & State University, Milledgeville, GA 31061-0490 ABSTRACT—Fossils from Agate Fossil Beds National Monument in western Nebraska have been a rich source of paleontological studies for many years. Fossil bird discoveries from the Monument have been far fewer than mammals and their reports have been sporadic and scattered throughout the literature. Although less common than mammals, the paleoavifauna of the Monument is very interesting in its level of diversity, ecological indicators, and from the perspective of historical biogeography with Old and New World representatives. The paleoavifauna has representatives from at least six families in four orders. Promilio efferus is the earliest record for a kite in North INTRODUCTION America (Brodkorb, 1964:274). Wetmore (1923:504) had ten- T HAS been more than ten years since Becker tatively placed efferus in the genus Proictinia Shufeldt (1915: I (1987a:25) briefly reviewed the fossil birds of the “Agate 301) from the late Miocene [latest Clarendonian or earliest Fossil Quarries.” The specimens described herein were col- Hemphillian, Long Island local fauna, Phillips County, Kan- lected in 1908 by field crews from the University of Nebraska sas; see Steadman (1981:171) for comments on age of Long State Museum, but have never been identified or reported upon Island local fauna].

    WEDNESDAY MORNING, NOVEMBER 3, 2004 ROMER PRIZE SESSION PLAZA BALLROOM A/B MODERATORS: RYOSUKE MOTANI AND RAYMOND ROGERS 8:00 Welcome 8:15 Beck, A.: THE ORIGINS OF MAMMALIAN LOCOMOTION: NEW METHODS FOR RECONSTRUCTING POSURE IN EXTINCT NON-MAMMALIAN SYNAPSIDS BECK, Allison, Univ. of Chicago, Chicago, IL The Synapsida, composed of living mammals and their extinct ancestors, are colloquially known as the ‘mammal-like reptiles.’ The extensive fossil record captures numerous transitional forms recording the transition from Permian, reptile-like pelycosaurs to primitive therians of the Triassic. A major part of this transition involved a change from a sprawling posture to one similar to the crouched posture of living small mammals such as the opossum. Despite our understanding of the postural endpoints, the question remains: What was the locomotory posture of taxa that are phylogenetically intermediate between pelycosaurs and modern mammals? Two major notions of postural change have been proposed, both supported by functional morphologic analyses and comparison to living mammals and reptiles. One suggests that intermediate taxa were capable of a dual-gait, much like modern crocodilians. The other outlines a series of increasingly upright intermediates. Neither hypothesis has been quantitatively evaluated. Here I set up a framework for interpreting function in extinct vertebrates, and apply it to reconstructing posture in extinct non-mammalian synapsids. Linear and angular measurements were taken on the limb and girdle bones of extant iguanian and varanid lizards, crocodilians, therian mammals and monotremes, and again on fossil synapsids. Multivariate and bivariate analyses were used to correlate suites of morphologic features with posture in the living forms.
