Relating to or composed of crinoids or crinoid remains; having the nature of crinoid material.
From 'crinoid' + '-ic' (adjectival suffix). Variant of 'encrinal' with different suffix formation.
Geologists use 'encrinic' to describe whole layers of rock made entirely from sea lily fossils—it's humbling to realize that thick sections of Earth's crust are basically ancient animal graveyards!
