| Summary: | ANGUILLA? CHICKASAWAE SCHWARZHANS AND STRINGER, 2020a FIG. 5F Material— six specimens, specimen figured, DMNH 2021-09- 6. Description and Remarks— Distinguishing characteristics of Anguilla ? chickasawae include a somewhat oval to ovate shape in well preserved specimens (sensu Smale et al. 1995) with a H/L ratio of approximately 66%, a convex inner face, a narrow, almost horizontal sulcus with a poorly-defined ostium and cauda. The posterior margin is commonly almost vertical. Stringer et al. (2020, fig. 5A–E) originally described A. ? chickasawae from the Ripley Formation (Maastrichtian) of Mississippi. Anguilla ? chickasawae differs from other Late Cretaceous or Paleogene anguillid otoliths by its much longer ostium. Schwarzhans and Stringer (2020a) postulated that A. ? chickasawae could represent a fossil genus of the Anguillidae or a closely related fossil family of which otoliths are not known presently. ... : Published as part of Stringer, Gary L. & Sloan, James Carson, 2023, First Cretaceous teleostean otolith assemblage (Arkadelphia Formation, upper Maastrichtian) from Arkansas, USA, early Gadiformes, and the Western Interior Seaway, pp. 1-39 in PaleoBios 40 (1994) on page 9, DOI: 10.5070/P940361192., http://zenodo.org/record/10913416 ... |
