Catalog entries: Spongurus pylomaticus
Original description: Shell subcylindrical or elongate ellipsoidal, approximately twice as long as broad. An inner, densely spongy core is surrounded by a narrow mantle of less dense meshwork. Entire surface usually sparsely covered with bristle-like spines, which in many specimens tend to be longer at the two poles of the main axis. At one pole is a pylome, usually surrounded by short, irregular teeth.
Remarks on original description: As indicated by Haeckel (1887, 343-345), the genus Spongurus is apparently cosmopolitan, this species, the only pylomatic member of the genus, has not been found anywhere but in the Antarctic, where it occurs in both the American and Indian Ocean sectors.
Geological Range:
Last occurrence (top): Extant. Data source: Lazarus et al. 2015 - "R age group"
First occurrence (base): within Quaternary Period (0.00-2.59Ma, base in Gelasian stage). Data source: Lazarus et al. 2015 - "R age group"
