A diverse vertebrate fauna, dominated by elasmobranch taxa, was collected from the upper Oligocene (Chattian) Chandler Bridge Formation in Summerville, Dorchester County, South Carolina. Nearly 3,500 teeth and dermal denticles are assigned to 29 species of sharks and rays, and our sample includes the oldest known occurrence of the whale shark, Rhincodon, as well as a new skate, Raja mccollumi sp. nov. The Chandler Bridge elasmobranch assemblage is comparable in species diversity to Chattian assemblages of Virginia and North Carolina, USA, and Germany. Notable absences from Germany include Rhincodon, Hemipristis, and Sphyrna zygaena, likely reflecting the influence of colder water on the North Sea Basin during the Chattian. Squaloids, pristiophoroids, and hexanchoids are known from Chattian deposits of the Albemarle Embayment (North Carolina), Salisbury Embayment (Virginia), and North Sea Basin, but these taxa are absent from the Chandler Bridge assemblage, perhaps because of shallow, warm water (20 to 25°C) conditions within the more southerly Charleston Embayment.

The following three gonad-infecting species of Philometra Costa, 1845 (Nematoda, Philometridae) were recorded from offshore perciform fishes in South Carolina, USA: Philometra carolinensis Moravec, de Buron et Roumillat, 2006 from the southern kingfish Menticirrhus americanus (Linnaeus) (Sciaenidae) (new host record), Philometra floridensis Moravec, Fajer-Avila et Bakenhaster, 2009 from the red drum Sciaenops ocellatus (Linnaeus) (Sciaenidae), and Philometra saltatrix Ramachandran, 1973 from the bluefish Pomatomus saltatrix (Linnaeus) (Pomatomidae). Findings of the first two species represent the second records since their original descriptions and P. floridensis was for the first time recorded from South Carolina estuaries. Detailed study of these nematode species, using both light (LM) and scanning electron microscopy (SEM), revealed the presence of minute caudal projections in the gravid female of P. carolinensis and four pairs of caudal papillae in the conspecific male; the cephalic and caudal ends of this species were for the first time examined by SEM. The related species P. carolinensis and P. floridensis, both parasitizing sciaenid fishes, can be distinguished from each other mainly by the presence/absence of oesophageal teeth, lengths of spicules and body lengths of gravid females. The morphology of North American specimens of P. saltatrix was found to be identical with that of specimens from Europe, thus confirming their conspecificity.

According to many reports, the endosperm of Arabidopsis thaliana (L.) Heynh. follows Nuclear-type development whereby the primary endosperm nucleus divides without cytokinesis, ultimately to produce a peripheral, multinuclear endosperm tissue. However, some features of endosperm development in seeds collected from populations in central South Carolina reveal striking differences from the Nuclear type of other Brassicaceae. Nuclei produced by the first division of the central or slightly chalazal primary endosperm nucleus quickly migrate to opposite poles on the longitudinal axis, where the chalazal nucleus immediately becomes enshrouded with dense cytoplasm. Divisions from that point onward are free-nuclear and frequent in the micropylar portion, which enlarges markedly as it becomes multinucleate. The chalazal endosperm is sometimes positioned in a different focal plane as a result of curvature of the immature seed toward amphitropous form. It does not enlarge appreciably and accumulates only 2-8 nuclei before it gradually degenerates, persisting until digested during maturation of the developing embryo. Thus, the functional endosperm is produced primarily by the micropylar chamber.

Three gonad-infecting species of Philometra Costa, 1845 were, for the first time, recorded from perciform fishes from estuarine and marine waters in South Carolina and Georgia, USA: Philometra charlestonensis sp. nov. from the scamp Mycteroperca phenax (Jordan et Swain) (Serranidae), P. saltatrix Ramachandran, 1973 from the bluefish Pomatomus saltatrix (Linnaeus) (Pomatomidae), and Philometra sp. from the Atlantic croaker Micropogonias undulatus (Linnaeus) (Sciaenidae). The new species is characterized mainly by males (body length 2.65–3.14 mm) with equally long, needle-like spicules (length 132–141 μm) and the gubernaculum (81–93 μm) bearing dorsal transverse lamella-like structures on its distal portion, the body length of gravid females (168–247 mm), the presence of a well-developed anterior bulbous inflation on the female oesophagus, and by the length of the first-stage larvae (544–597 μm). A key to gonad-infecting species of Philometra parasitizing marine and brackish-water fishes is provided.
