Last we have shale, which is composed of clay particles and has a finely layered or fissile appearance. This extremely mature sedimentary rock is made from the smallest particles that can be carried by wind or barely moving water and can be found thousands of miles away from the original source.The shale is fossiliferous and occurs as irregular partings and thin beds. The limestone and shale tend to grade indistinctly into each other. The large globular brachiopod Platystrophia ponderosa is abundant and, as in the Leipers Limestone, contributes to the nodular nature of the bedding.Question 22 (1 point).
