Afanasievella Nestell & Nestell, 2010

Afanasievella Nestell & Nestell, 2010: 22 .

TYPE SPECIES. — Afanasievella apachensis Nestell & Nestell, 2010 ( Nestell & Nestell 2010: 23, pl. 8, fig. 4, 6, pl. 9, fig. 1-5).

AGE AND LOCATION OF TYPE MATERIAL. — Upper Capitanian, Guadalupian, Middle Permian, West Texas, USA.

TAXON CODE. — 076.

STATUS. — Valid.

DIAGNOSIS. — “Test bipyramidal in shape, with three shells: spongy external shell, porous intermediate shell and microsphere. Between microsphere and intermediate shell six thin rod-like rays develop which continue outside of microsphere as primary threebladed radial beams extending outside as main spines. Between intermediate and external shells, radial thin and rod-like beams and secondary small conical spines are developed. The ends of the radial beams are bifurcated as are the apophyses that connect with each other and form the internal or basal layer of the spongy external shell. Three rows of the linear apophyses are developed at the distal end of the primary three-bladed radial beams.” ( Nestell & Nestell 2010: 22).
