Trigonosphaera Feng in Feng, Gu, Jiang & Jin, 2004
Trigonosphaera Feng in Feng, Gu, Jiang & Jin, 2004: 137.
TYPE SPECIES. — Trigonosphaera calvata Feng in Feng, Gu, Jiang & Jin, 2004 ( Feng et al. 2004: 142, pl. 3, fig. 1-7, pl. 4, fig. 1).
AGE AND LOCATION OF TYPE MATERIAL. — Upper Changhsingian (uppermost Permian), Dongpan section, Dalong Formation, Southern China.
TAXON CODE. — 306.
STATUS. — Valid.
DIAGNOSIS. — “Test consists of a single round-triangular cortical shell, without medullary shell and internal spicule. The shell is composed of two spongy layers. The two layers are similar in thickness, but different in structure: the inner layer is comprised of large, irregular pore frames and the outer layer, of small, irregular pore frames. Numerous beams connect the two layers.” (Feng in Feng et al. 2004: 137).
REMARK
Some centrally directed remains of the inner layer seem to suggest that there existed a central structure that was later dissolved by fossilization.
