title: Geologically Oldest Pediomyoidea (Mammalia, Marsupialiformes) from the Late Cretaceous of North America, with Implications for Taxonomy and Diet of Earliest Late Cretaceous Mammals

description: Terrestrial faunas of Turonian age are poorly known due to the paucity of the fossil record in North America and globally. The Smoky Hollow Member of the Straight Cliffs Formation, southern Utah, has yielded a rich assemblage of terrestrial vertebrates; among these, we herein recognize the geologically oldest members of Pediomyoidea. Two new species, <i>Scalaria martini</i>, gen. et sp. nov. and <i>Scalaria aquilana</i>, gen. et sp. nov., are recovered as members of Aquiladelphidae, sharing upper molar characters such as a subdivided B cusp, round and inflated cusps, and an anteroposteriorly expanded protocone. A fragmentary specimen is recognized as an indeterminate pediomyid with morphological similarities to <i>Leptalestes</i>. The occurrence of these distinctive groups in the Turonian prompted a re-evaluation of possible antecedents from earlier faunas, and a review of specimens referred to Aquiladelphidae. A phylogenetic analysis suggests that the Cenomanian tribosphenidan <i>Dakotadens</i> may belong within Aquiladelphidae. Of specimens referred to Aquiladelphidae, we recognize <i>Aquiladelphis laurae</i> as a valid species within the genus, and describe a new species of <i>Aquiladelphis</i> from the Judith River Formation of Montana, <i>Aquiladelphis analetris</i>, sp. nov. Two specimens from the ‘Edmontonian’ Williams Fork Formation, previously identified as <i>Aquiladelphis</i>, are here referred to a new species of <i>Glasbius</i>, <i>G. piceanus</i>, sp. nov. The presence of dentally derived marsupialiforms in the Turonian suggests that ecological drivers credited with dietary specializations among later Cretaceous taxa, such as proliferation of angiosperms and pollinating insects, were at work earlier than previously thought. http://zoobank.org/urn:lsid:zoobank.org:pub:E938B685-7F91-4BC2-85D6-3CDD501D5D88

title: A Transitional Mammalian Carnivore Community from the Paleogene–Neogene Boundary in Northern Kenya

description: The Paleogene–Neogene boundary is an important transitional time for the evolution of African fauna. Many taxa that evolved endemically in the Paleogene begin to wane in diversity, while new taxa, many of which will become exemplars of the modern African fauna, immigrate from Eurasia via newly opened terrestrial connections. The Paleogene–Neogene boundary is documented in the fossil record at Nakwai, in northern Kenya. Here we describe the mammalian carnivore fauna, which includes the earliest carnivoran records in Africa, and an interesting mix of Paleogene and Neogene hyaenodont taxa. The carnivoran fauna includes <i>Jinomrefu lakwanza</i>, gen. et sp. nov., the earliest barbourofelid in Africa, which has a transitional sabertooth morphology. An analysis of ecomorphological change in African mammalian carnivores across this boundary shows that hyaenodonts become more disparate in body size and more hypercarnivorous as they are displaced by invading carnivorans. This provides another test case for possible competition between carnivorans and hyaenodonts, a group that goes extinct in Africa and globally during the Neogene. http://zoobank.org/urn:lsid:zoobank.org:pub:D803E9DB-B2F1-497D-B796-57BED91BC744

title: A Basal Nonmammaliaform Cynodont from the Permian of Zambia and the Origins of Mammalian Endocranial and Postcranial Anatomy

description: Nonmammaliaform cynodonts were a diverse group of Permo-Triassic synapsids whose morphological evolution documented the beginning of many classic mammalian traits. Here, we describe a new basal cynodont from the upper Permian Madumabisa Mudstone Formation of Zambia’s Luangwa Basin as <i>Nshimbodon muchingaensis</i> gen. et sp. nov. The holotype, a relatively complete and undistorted cranium and articulated mandible with associated postcranial elements, is interpreted as the most complete and well-preserved example of a charassognathid cynodont, and preserves hitherto unknown details of charassognathid endocranial and postcranial anatomy. A phylogenetic analysis of 111 morphological characters from 25 therapsid taxa (including 15 Permo-Triassic cynodonts) supports a sister-taxon relationship between <i>Nshimbodon</i> and <i>Abdalodon</i>, including them with <i>Charassognathus</i> in a monophyletic Charassognathidae, and placing the family near the base of Cynodontia. In addition to its phylogenetic importance, <i>Nshimbodon</i> provides evidence of correlated transformations in the feeding system, neck, and shoulder, which are consistent with novel mammal-like locomotor and feeding mechanics in the earliest cynodonts. Lastly, given previous reports of charassognathids in the Karoo Basin of South Africa, the occurrence of <i>Nshimbodon</i> indicates that charassognathids, like the basal cynodont <i>Procynosuchus</i>, were geographically widespread in southern Pangea by Lopingian times. Continued collecting in the Madumabisa Mudstone Formation will lead to a better understanding of the formation’s Permian cynodont diversity and biostratigraphy, as well as the biogeographic structure of southern Pangean vertebrate assemblages prior to the Permo-Triassic mass extinction. http://zoobank.org/urn:lsid:zoobank.org:pub:143CE9D3-5742-4E92-B48F-164685F0907C

title: Insights on the dental evolution of walruses based on new fossil specimens from California

description: Twelve new specimens of fossil walruses are described from four Miocene units in California. The new material represents five taxa: (1) a specimen from the Santa Margarita Formation referred to <i>Imagotaria downsi</i>; (2) a specimen from the Valmonte Diatomite Member of the Monterey Formation referred to cf. <i>Pontolis magnus</i>; (3) six specimens from the Monterey Formation referred to a new species of <i>Pontolis</i> (<i>Pontolis barroni</i>, sp. nov.); (4) one specimen from the Oso Member of the Capistrano Formation referred to a new species of <i>Pontolis</i> (<i>Pontolis kohnoi</i>, sp. nov.); (5) three specimens from the Oso Member referred to a new genus and species (<i>Osodobenus eodon</i>, gen. et sp. nov.). A phylogenetic analysis suggests that both the Dusignathinae and an expanded concept of the genus <i>Pontolis</i> represent monophyletic groups. We provide phylogenetic definitions for clade names of odobenids. Two of the new species are represented by specimens of males, females, and juveniles. Analysis of these specimens shows that the dental anatomy of later diverging basal odobenids is more variable than previously considered. The specific pattern of variation is lineage specific and likely corresponds to the intermediate dental morphology of late Miocene odobenids. <i>Osodobenus eodon</i>, gen. et sp. nov., is the first basal odobenid with tusk-like canines, a longitudinally arched palate, and an enlarged infraorbital foramen. These features are plausibly correlated with benthic suction feeding in the odobenins (Pliocene to Recent) and so <i>Os. eodon</i> may represent a case of convergent evolution of benthic feeding in the late Miocene.

title: Using Manual Ungual Morphology to Predict Substrate Use in the Drepanosauromorpha and the Description of a New Species

description: Fossils of drepanosauromorphs, a clade of non-saurian diapsids, were once considered relatively rare in the Chinle Formation of the southwestern United States as well as in Upper Triassic rocks globally. Recent discoveries have shown that there are at least four drepanosauromorph taxa present in the Chinle Formation including <i>Dolabrosaurus aquatilis</i>, <i>Drepanosaurus</i> sp., <i>Ancistronychus paradoxus</i>, and a new genus and species described here, <i>Skybalonyx skapter</i>. This new taxon is represented by disarticulated manual unguals and is preserved in a microvertebrate bearing bone-bed in the Blue Mesa Member (∼223–220 Ma) of the Chinle Formation at Petrified Forest National Park, which was deposited in a fluvio-lacustrine setting in equatorial Pangaea during the mid-Norian. Different types of substrate use have been hypothesized for the Drepanosauromorpha. By performing discriminant function analyses using the manual unguals of 173 mammal and 13 reptile species with known substrate use, we hope to infer the ecomorphology of drepanosauromorphs. We found that the enlarged second manual unguals of <i>Drepanosaurus</i> sp. are similar to hook-and-pull digging taxa (e.g., <i>Tamandua mexicana</i> and <i>Cyclopes didactylus</i>) although the smaller manual unguals referred to this taxon (likely pertaining to digits other than digit II) are similar to modern arboreal taxa. Our results support the inference of arboreality in some drepanosauromorph species. However, we found that the manual unguals of <i>Ancistronychus paradoxus</i> and <i>Skybalonyx skapter</i> fit within the range of variation of modern fossorial and subterranean taxa, which expands the functional diversity of the Drepanosauromorpha within the Chinle Formation.

title: Late Pleistocene mammals from Kibogo, Kenya: systematic paleontology, paleoenvironments, and non-analog associations

description: We report on the Late Pleistocene (36–12 ka) mammals from Kibogo in the Nyanza Rift of western Kenya, providing (1) a systematic description of the mammal remains, (2) an assessment of their paleoenvironmental implications, and (3) an analysis of the biogeographic implications of non-analog species associations. Kibogo has yielded one of the largest paleontological assemblages from the Late Pleistocene of eastern Africa, and it is dominated by grassland ungulates (e.g., equids and alcelaphin antelopes), including an assortment of extralimital (e.g., <i>Equus grevyi</i>, <i>Ceratotherium simum</i>, <i>Redunca arundinum</i>) and extinct species (<i>Syncerus antiquus</i>, <i>Damaliscus hypsodon</i>, <i>Megalotragus</i> sp.). The composition of the fauna, in conjunction with the soils and topography of the region, indicate the local presence of edaphic grassland situated within a broader environment that was substantially grassier and likely drier than at present. In contrast to non-analog faunas from higher latitudes (e.g., North America and western Eurasia), the climatic niches of non-analog species associations strongly overlap, indicating that non-analog climate regimes during the Late Pleistocene of eastern Africa are not necessary to account for the former association of presently allopatric species. The Kibogo faunas add to a growing body of evidence implying that the composition of present-day African herbivore communities is distinct from those of the geologically recent past.
