The Echinoid Directory

• Test small (holotype 23 mm long), subcircular in outline, flat oral surface. Only known specimen crushed.
• Apical system central, tetrabasal.
• Petals of equal length, broad, closed, with wide interporiferous and poriferous zones; pores conjugate, outer pores slit-like, inner pores circular, ambulacral plates with single pores beyond petals.
• Peristome anterior, small.
• Periproct supramarginal, very wide and low, overhung by an aboral canopy, with a broad subanal platform extending posteriorly.
• Bourrelets strongly developed, tooth-like and weakly projecting.
• Phyllodes depressed between bourrelets, broad, no other details known.

Upper Cretaceous (Maastrichtian) of Spain.

Fauraster priscus Lambert, in Lambert & Thiery, 1924, p. 396; by original designation.

• Only the type species.

Irregularia; Cassiduloida; Faujasiidae; Stigmatopyginae.

Subjective junior synonym of Rhynchopygus d'Orbigny, 1856.

Fauraster is similar to Stigmatopygus, but has a wider subanal platform and no adapical notch to its periproct. The periproct position, the presence of the wide subanal platform and the lobe-like upper canopy to the periproct links Fauraster to Rhynchopygus, but it differs from that taxon in having well developed petals.

Kier (1962) believed Fauraster to be most similar to Faujasia in having short, closed, equal petals, a flat adoral surface and tooth-like bourrelets. Fauraster is distinguished from Faujasia by its supramarginal rather than inframarginal periproct and by its more flattened test.
