Opis:: A terrestrial crustacean, the crayfish, creates widespread fine-scale landforms (mounds or "chimneys") on the floodplain of the Roanoke River in eastern North Carolina, U.S.A. These mounds are typically 12 cm high and 8 cm in diameter, and are composed of extremely high concentrations of clay. Non-crayfish-affected soils on the floodplain, regardless of coarser-scale landform type, are dominated by sand, illustrating that crayfish are a primary mechanism for concentrating clay and creating spatial heterogeneity on the floodplain.

Opis:: Remingtonocetid cetaceans are a group of stem whales known from the Indo-Pakistan and North African Tethys Ocean. An unusual tooth was discovered by Peter J. Harmatuk in 1973 in the middle Eocene Superior Stone Quarry (now the Martin Marietta Quarry) near Castle Hayne, North Carolina, USA. Here we identify this tooth as a premolar of a possible member of the Remingtonocetidae, which would extend the range of this family across the Atlantic to eastern North America. This partial tooth includes most of the crown (missing the mesial end) and the posterior root. The tooth bears a single central cusp and a worn accessory cusp on the posterior end. This tooth most closely resembles premolars of Remingtonocetus and is rather dissimilar to premolars of other archaeocetes known from the middle Eocene of North America, such as the families Protocetidae and Basilosauridae. This new record potentially expands the geographic distribution of the amphibious cetacean family Remingtonocetidae across the Atlantic.
