How does a fossil limestone become lithified
WebMost fossils that exhibit “soft part” preservation are carbonizations. Examples include many plant fossils (also known as compressions), insect fossils, and the famous fossils of the Burgess Shale.

To do this, hand samples (samples of the rock layer that are small enough to be held in one's hand) are used. Here geologists make interpretations about the individual grains such as size, mineral composition, and shape (Heinz and Aigner, 2003).

Sometimes the fossilized remains of the organism are preserved in the rock, other times recrystallization during lithification has destroyed the remains. Limestones are very common sedimentary rocks.
WebHow do coquinas form? That is, where does the sediment come from and how does it become lithified to make a rock? Coquinas are formed by the deposition and cementation of mineral or organic particles on the floor of oceans or other bodies of water. This is a sample of limestone.
