Material examined

UNITED STATES OF AMERICA – Alabama • 54 otoliths; GLS otolith comparative collection (44 specimens), GSA 157.1, GSA 157.2, GSA 157.3, GSA 157.4, GSA 157.5, GSA 157.6, GSA 157.7, GSA 157.8, MSC 39060View Materials, WSU CC 471.1.

Description

Sagittae small to medium-sized (up to 4 mm), elliptical in shape. Dorsal margin very broadly and unevenly arched, small posterodorsal dome. Posterior margin slightly obliquely truncated or slightly incurved. Ventral margin smooth, very broadly and unevenly curved.Anterior margin has fairly prominent rostrum with excisura. Inner face strongly convex, with well-defined heterosulcoid-type sulcus covering at least 75% of length of otolith. Ostium moderately narrow, subquadrate shape, shorter than cauda. Cauda very narrow (about one-half or less than width of ostium). Cauda longer than ostium, has parallel sides, posterior portion bent sharply downward. Crista superior raised along horizontal portion of the sulcus; crista inferior is weakly developed. Shallow area extends along crista superior and upward flexure of ostium. Outer face somewhat concave, generally with irregular surface.

Remarks

This species is known to occur within the middle Eocene Weches and Cook Mountain formations at several localities in Texas, and it has also been reported from Alabama, Louisiana, and Mississippi ( Frizzell & Dante 1965; Nolf 2013). The type material of this species was collected from the Lisbon Formation at site AMo- 4 in Monroe County, Alabama, where it was reported as common by Frizzell & Dante (1965).

Stratigraphic and geographic range in Alabama

Orthopristis burlesonis  specimens were recovered from the “upper” Lisbon Formation at site ACh-8 and the Gosport Sand at site ACl-4. Bartonian, zones NP16 and NP17.
