Crinoids, like other members of the phylum Echinodermata, are exclusively marine animals with pentaradial symmetry and water-vascular systems. Though some groups have lost the stalk in adult forms, crinoids are considered to follow the stalked, radial morphology, as the stalkless forms are derived from stalked ancestors.the crinoidal limestone compared to that observed from surface drilling. • There are several steep to vertical dipping north-northeast trending structural zones hosting mineralisation in the mine area with new parallel structures identified in ABUG001 and ABUG002.
