Calcite

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).

Chordate

A chordate is an animal belonging to the phylum Chordata; chordates possess a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail, for at least some period of their life cycle.

Cothurnocystis

Cothurnocystis is a genus of small, enigmatic echinoderms that lived during the Ordovician.

Crinoid

Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata).

Crinozoa

Crinozoa is a subphylum of mostly sessile echinoderms, of which the crinoids, or sea lilies, are the only extant members.

Cystoidea

Cystoidea is a class of extinct crinozoan echinoderms, termed cystoids, that lived attached to the sea floor by stalks.

Echinoderm

Echinoderm is the common name given to any member of the phylum Echinodermata (from Ancient Greek, ἐχῖνος, echinos – "hedgehog" and δέρμα, derma – "skin") of marine animals.

Gill

A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide.

Gill slit

Gill slits are individual openings to gills, i.e., multiple gill arches, which lack a single outer cover.

Mitrate

Mitrates are an extinct group of stem group echinoderms, which may be closely related to the hemichordates.

Paleozoic

The Paleozoic (or Palaeozoic) Era (from the Greek palaios (παλαιός), "old" and zoe (ζωή), "life", meaning "ancient life") is the earliest of three geologic eras of the Phanerozoic Eon.

Polyphyly

A polyphyletic group is a set of organisms, or other evolving elements, that have been grouped together but do not share an immediate common ancestor.

Starfish

Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea.

Stylophora

The stylophorans are an extinct, possibly polyphyletic group allied to the Paleozoic Era echinoderms, comprising the prehistoric cornutes and mitrates.
