OSMEROIDES AGASSIZ, 1837

OSMEROIDES SP.

FIG. 5E View Figure 5

Material— three specimens, specimen figured, DMNH 2021-09- 05 About DMNH . About DMNH

Description and Remarks— The three small specimens assigned to Osmeroides are slightly oval shaped (sensu Smale et al. 1995) with a somewhat irregular dorsal margin and mostly smooth ventral margin. The dorsal field is much smaller than the ventral field. There is a heterosulcoid-type sulcus that is located primarily supramedially with a very slight downturn at the posterior of the slanted cauda. The inner face is convex, while the outer face is concave. The Arkadelphia specimens are similar to the Osmeroides sp. described and illustrated from the Ripley Formation in northeastern Mississippi by Stringer et al. (2020). Due to their small size and poor preservation, the assignment is tenuous, and a species determination is not possible.
