This classification of coprolite gets its name from the Greek words, alocos, meaning furrowed, and kopros, meaning dung. It differs from other coprolite ichnogenera in often being arcuate in lateral view and sub-rounded in cross-section with regularly spaced, thin, longitudinal grooves.

Coprolite with Longitudinal Striations

We don't know what creature created this furrowed coprolite. Although size and configuration vary somewhat, sphincter sculptures with striations have been found in sediments that were once part of fresh water stream environments dating from the Permian through the end of the Cretaceous. Most furrowed coprolites do not have inclusions. This one is unique in that it contains tiny little fish bone and scale inclusions.
