A New Species

Palynomorph assemblages dominated by dinoflagellate cysts are described from seventeen samples from the Rabot Member of the Santa Marta Formation at Ekelöf Point, eastern James Ross Island, Antarctic Peninsula. Although the assemblages are of relatively low diversity, the dinoflagellate cyst taxa recorded indicate a mid to late Campanian (Late Cretaceous) age. Changes in species diversity, dominance and gonyaulacacean ratio suggest a gradually reducing distance from shore during deposition, with a return to more offshore conditions towards the section top. A new species of dinoflagellate cyst, Isabelidinium papillum, is described.

Dorsal Margin

A new mesoeucrocodylian (Crocodyliformes) is described from the Laje do Coringa site, earliest Late Cretaceous (early Cenomanian) of the São Luís Basin, northeastern Brazil. Due to the likely hetorodonty indicated by distinct alveoli shapes, Coringasuchus anisodontis gen. et sp. nov. is tentatively referred to the Notosuchia and distinguished from other members of this clade by the presence of obliquely implanted teeth with the main axis directed anterolingually-toposterolabially and the presence of alveoli that are distinctively raised above the level of the dorsal margin of the dentary. The material further confirms the interpretation that the fossil concentration of the Laje do Coringa site is the result of multiple reworking events from previous deposits, but the degree of time-averaging was possibly higher than previously suspected.
