A summary of museum and literature records of ground sloths collected from South Carolina is presented. The ground sloth record in South Carolina consists of three genera, Eremotheirum with two species, Megalonyx with three species and Paramylodon with one species. Three of these species, Eremotherium eomigrans and Megalonyx leptostomus from the Blancan and Megalonyx wheatleyi from the Irvingtonian are new records for the state. An early Pliocene specimen of M. leptostomus is the earliest record of sloths from South Carolina. The fossil record of sloths in the state extends from the Pliocene (Blancan) through the Pleistocene (Late Rancholabrean) and is confined to sedimentary deposits on the Coastal Plain. © PalArch Foundation.

A single specimen of Tantilla alticola was collected from Parque Nacional G. D. Omar Torrijos Herrera of Coclé Province, Republic of Panama. This record fills in a gap in the distribution for this species within the cloud forests of Central America. © 2013 Check List and Authors.

Heavily tuberculated glyptosaur osteoderms were collected in an active limestone quarry in northern Berkeley County, South Carolina. The osteoderms are part of a highly diverse late Paleocene vertebrate assemblage that consists of marine, terrestrial, fluvial, and/or brackish water taxa, including chondrichthyan and osteichthyan fish, turtles (chelonioid, trionychid, pelomedusid, emydid), crocodilians, palaeopheid snakes, and a mammal. Calcareous nannofossils indicate that the fossiliferous deposit accumulated within subzone NP9a of the Thanetian Stage (late Paleocene, upper part of Clarkforkian North American Land Mammal Age [NALMA]) and is therefore temporally equivalent to the Chicora Member of the Williamsburg Formation. The composition of the paleofauna indicates that the fossiliferous deposit accumulated in a marginal marine setting that was influenced by fluvial processes (estuarine or deltaic). The discovery of South Carolina osteoderms is significant because they expand the late Paleocene geographic range of glyptosaurines eastward from the US midcontinent to the Atlantic Coastal Plain and provide one of the few North American records of these lizards inhabiting coastal habitats. This discovery also brings to light a possibility that post-Paleocene expansion of this group into Europe occurred via northeastward migration along the Atlantic coast of North America. © 2016, The Paleontological Society.

A diverse vertebrate assemblage was recovered from the Eutaw Formation along a stretch of Luxapalila Creek in Lowndes County, Mississippi. The assemblage is dominated by elasmobranchs but also includes osteichthyans (seven species), archosaurs (one crocodilian, two dinosaurs), and turtles (trionychid and chelonioid). Twenty one elasmobranch taxa were identified (14 selachians and seven batoids), including new species Meristodonoides multiplicatus, Lonchidion cristatum, and Cantioscyllium grandis. Our sample also enabled us to expand the known range of variation for some other poorly diagnosed species. The elasmobranch assemblage consists predominantly of species with presumed benthic habits (14), including the orectolobiform sharks and sclerorhynchid rays, whereas the seven lamniform sharks represent pelagic species. We believe that the sharks and rays inhabited a warm-water, nearshore marine environment.

Two new species of the myliobatid ray Pseudaetobatus Cappetta, 1986 are described from Eocene localities in three different states within the southeastern United States. Pseudaetobatus belli sp. nov. was recovered from south Alabama and southeast Mississippi from units within the lower Eocene portion of the Tallahatta Formation, as well as older strata of the underlying Hatchetigbee Formation. This species differs from the type species, P. casieri Cappetta, 1986, in that teeth are larger in overall size, and distal-most lateral teeth are less wide and have a shorter, less pronounced distal projection but more sharply basally curved margin. Pseudaetobatus undulates sp. nov. occurs within the upper Eocene Dry Branch Formation of south-central South Carolina, and this species is easily distinguished from P. casieri and P. belli sp. nov. By distal-most lateral teeth that are conspicuously sinuous in labial and lingual views. In addition to possessing features unique to each species, both P. belli sp. nov. and P. undulatus sp. nov. possess an additional lateral tooth morphology that is unknown in the type species. These new specimens significantly extend the paleogeographic distribution of Pseudaetobatus, and the genus is now known to occur virtually throughout the entire Eocene. © Palaeontological Association March 2015.
