“…Regardless, Sanders & Barnes (2002b, p. 317) remarked upon the similarity of the vertebrate assemblages from the Chandler Bridge Formation and the underlying Ashley Formation and concluded that the "two formations belong to the same biostratigraphical interval (NP24) and that very little time (probably no more than about 2 My) elapsed between the deposition of these two units." The lower two beds of the Chandler Bridge Formation have yielded dinoflagellates assignable to the dinoflagellate zone D14 (Katuna et al 1997), which are correlative with zones NP24 and 25 (Katuna et al 1997 29.0À28.75 Ma, and reported four new Strontium dates ranging from 24.7À24.5 for the Chandler Bridge Formation and a date from the overlying Edisto Formation of 23.5 Ma. Strontium isotope ratios from the Chandler Bridge Formation and overlying Edisto Formation constrain an age of 24.7À23.5 Ma (Weems et al, 2016).…”

“…Calcareous nannoplankton reported by Edwards et al (1997) confirmed assignment of the Ashley Formation to zone NP24 or possibly NP25; the more convincing assignment to zone NP24 is followed here (see Systematic review of Eomysticetidae, below). D14 which is broadly correlative with zones NP24 and NP25 (Katuna et al 1997), and no finer biostratigraphical resolution is currently available; newly reported Strontium isotope dates indicate an age of 24.7À23.5 Ma (Weems et al 2016). The Jinnobaru Formation (Kyushu, Japan), which produced Yamatocetus, has not yielded any direct dates.…”

Eomysticetids represent a worldwide, short-lived radiation of archaic baleen-bearing mysticetes that elucidate morphofunctional shifts and ontogenetic change amongst early Neoceti. Fossils of eomysticetids are now recorded from Oligocene marine rocks along the margins of the North Pacific (Japan), North Atlantic (South Carolina), and the Southern Ocean (New Zealand). The assemblage from New Zealand is diverse, with five species in three genera present during the Duntroonian stage (Chattian, 27.3À25.2 Ma). A new genus and species of eomysticetid from the lower Kokoamu Greensand of New Zealand, Matapa waihao gen. et sp. nov., increases the known diversity of Southern Hemisphere eomysticetids. Matapa uniquely exhibits a rounded margin of the occipital shield, and shares a mosaic of features seen in Northern Hemisphere eomysticetids such as a large squamosal prominence, an inflated and posteriorly rounded paroccipital process, and a double-faced posterior bullar facet with longitudinal ridges. The holotype specimen of Matapa waihao is ontogenetically immature, but ontogenetically static tympanoperiotic characters that diagnose this new species are shared by referred adult specimens. Matapa is uppermost Whaingaroan (28.1À27.3 Ma) in age, the oldest eomysticetid from New Zealand. Fossils of Matapa are recovered from both the modern west and east coast of New Zealand which, during the Oligocene, were on the margin of the Southern Ocean. Inclusion of Matapa within an earlier published cladistic analysis recovers Matapa as the earliest diverging member of the New Zealand eomysticetid clade, and confirms eomysticetid monophyly. The taxonomy, morphology and geochronological age of all known eomysticetids are reviewed.http://zoobank.org/urn:lsid:zoobank.org:pub:EE1CB5CC-618B-4ABA-9D97-5B9DEDD3470E

Peer Review #1 of "New records of the archaic dolphin Agorophius (Mammalia: Cetacea) from the upper Oligocene Chandler Bridge Formation of South Carolina, USA (v0.1)"

The stem odontocete Agorophius pygmaeus (Ashley Formation, lower Oligocene, South Carolina; 29.0-26.57 Ma) has been a critical point of comparison for studies of early neocete evolution owing to its early discovery as well as its transitional anatomy relative to archaeocete whales and modern odontocetes. Some time during the late nineteenth century the holotype skull went missing and has never been relocated; supplementary reference specimens have since been recently referred to the species from the Ashley Formation and the overlying Chandler Bridge Formation (upper Oligocene; 24.7-23.5). New crania referable to Agorophius sp. are identifiable to the genus based on several features of the intertemporal region. Furthermore, all published specimens from the Chandler Bridge Formation consistently share larger absolute size and a proportionally shorter exposure of the parietal in the skull roof than specimens from the Ashley Formation (including the holotype). Furthermore, these specimens include well-preserved ethmoid labyrinths and cribriform plates, indicating that Agorophius primitively retained a strong olfactory sense. These new crania suggest that at least two species of Agorophius are present in the Oligocene of South Carolina, revealing a somewhat more complicated taxonomic perspective.

“…The Chandler Bridge Formation was deposited in a coastal marine setting, with estuarine, lagoonal, beach, and shallow marine environments being represented (Sanders et al 1982;Weems and Sanders 1986;Katuna et al 1997;Cicimurri and Knight 2009). There apparently was little fluvial input into this depositional environment (contra Katuna et al 1997) because the preserved vertebrate fauna overwhelmingly consists of marine sharks and rays (Cicimurri and Knight 2009), marine bony fishes (e.g., Fierstine and Weems 2009), cetaceans, dugongs, sea turtles, and sea birds (Sanders 1980).…”

A New Species of Bairdemys (Pelomedusoides: Podocnemididae) from the Oligocene (Early Chattian) Chandler Bridge Formation of South Carolina, USA, and Its Paleobiogeographic Implications for the Genus

A new species of podocnemidid pleurodire turtle, Bairdemys healeyorum, is described from the upper Oligocene Chandler Bridge Formation of South Carolina, USA, on the basis of a nearly complete shell found with associated skull fragments, lower jaw, girdle elements, and limb elements. This is the first record of an Oligocene pleurodire turtle from North America. The shell and lower jaw are unique in detail but similar in overall morphology to equivalent parts of Bairdemys venezuelensis and B. sanchezi. The plastron of this new species also shares many features with the previously described Maryland Miocene species of podocnemidid, ''Taphrosphys'' miocenica, so the Miocene taxon is here referred to Bairdemys. In the Oligocene and Miocene, North and South America were separated by broad expanses of salt water, so Bairdemys probably was salt-water tolerant and reached North America by ''island hopping'' from South America across the Caribbean Sea.
