Meekospira peracuta

Catalog Number: CG-0002

Meekospira peracuta is a high-spired gastropod. This specimen was found next to a concretion in shale. The large outer rim of the concretion is visible as a curved piece on the rock. The tip of the snail was more prominent when first pulled out, and the attempted removal of the clay on the shale made me lose it.

This genus and species have been known since 1860. They were first described by F. B. Meek and A. H. Worthen, who based their description on a journal article about Carboniferous fossils from Illinois and other western states.

The species existed between 326 to 303 million years ago. Examples from within the genus range from 388 to 252 million years ago.
