The Upper Silurian Tonoloway Limestone at Pinto, Maryland, is divided into 3 informal members on the basis of field, paleontologic, and petrographic studies. The lower member is characterized by thin bedding, stromatolites, gypsum pseudomorphs, intraclasts, and mud cracks. The rocks typically are laminated micrite and pelmicrite.

Micrite is lime mud, carbonate of mud grade. Micrite as a component of carbonate rocks can occur as a matrix, as micrite envelopes around allochems or as peloids.
