How is fossil limestone lithified

WebAll that may be left is the lithified coil of sediment (perhaps consisting of siliciclastic sediment) that filled the inside of the snail’s shell. This tells us what the inside of the snail’s shell looked like, but not much about the external morphology of the shell. WebLimestone can contain various types of fossils, ranging from microfossils to macrofossils, depending on the depositional environment and age of the rock. Microfossils found in limestone can include foraminifera, coccoliths, and diatoms, while macrofossils can include shells of marine invertebrates such as mollusks, bryozoans, and corals.
