“…Therefore, even if a small component of C4 plants had been present in the Eocene-Oligocene Great Plains, most animals would have likely selected C3 plants, largely reducing the C4 isotopic signal in tooth enamel. Finally, our results in terms of habitat preference are generally consistent with the data obtained in most previous morphological and sedimentological studies (Clark et al, 1967;Retallack, 1983;Lander, 1998;Wall and Hauptman, 2001).…”

“…Merycoidodon, whose estimated body weight is ∼50 kg, had five toes on the front legs and four on the back. It first appeared in the late middle Eocene (Duchesnean NALMA, ∼38 Ma) and became extinct in the late Oligocene (Arikareean NALMA, ∼ 28 Ma; Lander, 1998). Lander (1998) suggested that Merycoidodon was a mixed browser-grazer inhabiting gallery forests.…”

Lander (1998) suggested that Merycoidodon was a mixed browser-grazer inhabiting gallery forests. Slightly in contrast with this interpretation, Clark et al (1967) indicated a preference of late Eocene Merycoidodon for savanna or savanna-forest habitats.…”

“…Recent work also demonstrates that this faunal province extended as far south as Panama, and has interesting occurrences at range extremes such as anthracotheres (Rincon et al, 2013) and amphicyonids. During the Hemingfordian, oreodonts are rare at Thomas Farm at a time when they were common elsewhere in North America (e.g., Lander, 1998). The distinct climatic regime of the southeastern U.S., including Florida, also provided a refugium for some late surviving species during the Hemphillian (Tedford et al, 2004).…”

This paper presents the history and development of the vertebrate paleontology (VP) program since its inception at the Florida State Museum (name changed to Florida Museum of Natural History in 1988) over the past 60 years. Given the rich and ubiquitous 40-million-year fossil record exposed in Florida and general public interest in extinct life, it is not surprising that paleontology has continued to be a cornerstone of the museum. The impact of two aspects of this program is highlighted; i.e., (1) the “formative decade” from 1956 to 1965; and (2) the development of the VP collection and related activities over the past 60 years. VP has benefitted greatly from dedicated and passionate people involved in this program, including curators, staff, undergraduates, volunteers, and 80 graduate students. Other topics covered in this history include leadership, infrastructure, research, education, and outreach. Outcomes have included a collection that has grown to almost a half million digitized specimens, more than 15 million dollars of grant-supported projects, active, year-round field work, about 400 peer-reviewed papers published, and innovative exhibitions and public programs. The unique identity of the VP program and its recognition among peers both nationally and internationally results from the positive influences of these foundational core and related activities over the past 60 years.

“…Twelve of these clades are represented by generic level mammalian phylogenies and the last is a specific level phylogeny of Alligatoridae. The taxa and source cladograms are: Camelidae (Honey et al., 1998), Oxyanidae and Hyaenadontidae (Gunnell, 1998), Oreodontoidea (Lander, 1998), Multituberculata (Rougier et al., 1997), “miacoids” (Flynn, 1998), Mesonychidae (Zhou et al., 1995), Borophaginae (Wang et al., 1999), Proboscidea (Lambert and Shoshani, 1998), Antilocapridae (Janis and Manning, 1998), Tapiroidea and relatives (Colbert and Schoch, 1998), Equidae (MacFadden, 1998) and Alligatoridae (Brochu, 1999). Source taxon cladograms and observed stratigraphic ranges are provided in Fig.…”

Telling time from fossils: a phylogeny‐based approach to chronological ordering of paleobiotas

The potential for using fossils for temporal ordering of sedimentary rocks is as old as historical geology itself. In spite of this, however, most current biostratigraphic and biochronologic techniques do not make use of phylogenetic information, but rely instead on some measure of species' presence or absence or their turnover in the fossil record. A common phylogenetic approach to biochronology has been to use ''stage of evolution'' arguments, whereas more rigorous, cladogram-based methods have been proposed but have seen little use. Cladistic biochronologic analysis (CBA) is developed here as a new method for determining biochronologic order between paleobiotas based on the phylogenetic relationships of their constituent taxa. CBA is adapted from Brooks' parsimony analysis, and analyzes syntaxon information from clades that transcend a number of paleobiotas to determine relative temporal order among these paleobiotas. Because CBA is based on phylogenetic information, it is suited to problems where a good fossil record is available, but where stratigraphic or chronologic relationships are poorly constrained, such as the terrestrial vertebrate record. A practical example, based on the Cenozoic fossil record of North America, pits CBA against a test case in which the correct temporal order of biotas is known beforehand. The method successfully recovers correct temporal order between paleobiotas with reasonable levels of support, and is also shown to outperform a previously proposed cladistic biochronologic method. In a second example, CBA is used to achieve the first empirical temporal ordination for several Late Cretaceous localities in the Gobi Desert that produce fossils crucial to the understanding of modern amniote clades, but which have poorly resolved temporal relationships. CBA is sensitive to large amounts of extinction and poor sampling of the fossil record, but problems such as gaps in the fossil record (Lazarus taxa) can be dealt with efficiently through a number of a priori and a posteriori scoring techniques. CBA offers a novel approach for biochronologic analysis that is independent of, but complementary to and readily combinable with other chronologic ⁄ stratigraphic methods.
