A taxonomic subclass or group of ancient echinoderms that includes crinoid-like creatures with segmented arms.
From encrinoid + -ea (scientific Latin plural/classification suffix). This is a formal scientific classification term for organizing fossil creatures.
Encrinoidea represents a crucial branch in the family tree of echinoderms—they're the sophisticated cousins of starfish and sea urchins, showing how complex ocean life became millions of years ago!
