Types of coral fossils.

Fossiliferous limestone is a limestone that contains obvious and abundant fossils. They are usually marine invertebrates such as brachiopods, crinoids, mollusks, gastropods, and coral.

Fossil eggs worldwide are very rare. In almost all cases an egg-shaped fossil is something else. Most fossil "eggs" are weathered and rounded rocks, rather than fossils. siderite nodules and concretion s can have smooth, oval shapes and may appear like eggs.
