Material examined

UNITED STATES OF AMERICA – Alabama • 2 otoliths; MSC 35076.3, WSU CC 470.3.

Description

These two specimens have numerous salient characteristics of Lactarius . These include the shape of the otolith, the type and orientation of the ostium and cauda, the depressed, almost linear area above the crista superior, and a ventral furrow. The specimens may represent Lactarius amplus , but their preservation prohibits this determination.

Remarks

These specimens may represent a different species. However, better-preserved, additional adult specimens would be required to make this determination.

Stratigraphic and geographic range in Alabama

The specimens in our sample were found in the “upper” Lisbon Formation at site ACh-8. Bartonian, zones NP16 and NP17.
