thank you for the information. But what is the question?
Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. The ratio of clay to other minerals is variable.
so the statement is FALSE

A rock called shale is formed from the skeletons of ancient coral animals.
