A rad Ophiomorpha in some turbiditic sandstones from the Book Cliffs, Utah.  This trace fossil is a burrow made by a shrimp, held together with fecal pellets plastered to the wall in order to stabilize the structure in noncohesive, shifting sand.  The bumpy, rugose texture of the trace is a result of the little fecal pellets.  NEAT, HUH!?
