MURAENANGUILLA ? SP.

FIG. 5H View Figure 5

Material— two worn, broken specimens, specimen figured, DMNH 2021-09-08.

Description and Remarks— The Muraenanguilla ? specimens from the Arkadelphia Formation are oval in shape (sensu Smale et al. 1995) with a H/L ratio of approximately 66%. The convex inner face has a fairly deep, moderately narrow sulcus. It is difficult to differentiate the ostium and cauda. The dorsal margin tends to be irregularly curved, while the ventral margin appears to be smooth and regularly curved. These specimens resemble Muraenanguilla unionensis Schwarzhans and Stringer (2020b) , which is known from the Ripley and Owl Creek formations (Maastrichtian) of Mississippi (Stringer et al. 2020). Unfortunately, the specimens are not preserved well enough to make any definitive identification. The genus is also known from the Paleogene of Europe ( Schwarzhans 2019), the Upper Cretaceous Coon Creek type locality in Tennessee ( Stringer 2016b), and the upper Maastrichtian Severn Formation in Maryland ( Huddleston and Savoie 1983, Stringer and Schwarzhans 2021).
