Description
Calyx 1.5mm long and 1.4mm wide with arms possibly incomplete. Arms present with 0.24mm in width, 0.95mm in length. Total length of calyx and distal part of stalk preserved 6.5mm. Stalk 0.32mm in width, stalk columnals approx 1mm in length. (Fig. 13)
Genetic data for this taxa with new GenBank accession numbers are provided in Table 2
Diagnosis
Morphologically close to
Hyocrinus foelli
Roux and Pawson 1999
but incomplete specimen prevents full identification. Forms a unique monophyletic clade distinct from other AB01 specimens. No genetic matches on GenBank or Barcode of Life Database.
Ecology
Specimen observed live on a small potato-sized polymetallic nodule from the eastern CCZ abyssal plain.
