Descripción
A fossiliferous limestone composed of coarse shells or shell fragments which is loosely cemented by an infiltration of carbonate of lime; its name derives from the Spanish word for 'cockleshell.' Coquina is a detrital rock because it is formed from debris and is distinguished from coquinoid limestone which is formed in situ and is composed of shell material in a fine-grained matrix.
