Often times the fossil and the surrounding rock layer are made up of different minerals that erode or wear away at different rates. As the rock around the fossil is eroded away, the fossil inside remains intact because it is a harder material.Crinoids Fossil rock Lake Michigan geode/ raw brachiopod geode Bryozoa craft beach stone / specimen supply (125) $ 36.00.

Crinoids. Crinoids are echinoderms and are true animals even though they are commonly called sea lilies. The body lies in a cup-shaped skeleton (calyx) made out of interlocking calcium carbonate plates. Arms attached to the calyx also have a plated skeleton and are used to capture food particles. In most species, the calyx is anchored to the ...Often, sea lily fossils may be hard to distinguish right away if you are looking specifically for the sea lily arms. Often pieces of stem or just the caylx (body/cup) is found. The example below is one of these types of fossils.
