Palaeosphaera Renz, 1990

Palaeosphaera Renz, 1990: 372 .

TYPE SPECIES. — Palaeosphaera micra Renz, 1990 ( Renz 1990: 372, pl. 1, fig. 7, 9).

AGE AND LOCATION OF TYPE MATERIAL. — Upper Ordovician (Katian), Nevada, USA.

TAXON CODE. — 070.

STATUS. — Junior synonym of Secuicollacta Nazarov & Ormiston, 1984 (herein).

DIAGNOSIS. — “A relatively small, single, non-pylomate sphere with four to six moderate primary spines. No secondary spines or internal structure. Primary spines are straight, round in cross section and taper distally. Pores are irregularly rounded, small, slightly variable in size.” ( Renz 1990: 372).

REMARKS Examination of one of the published photos of the type species ( Renz 1990: pl. I, fig. 9) clearly shows that the spines in the northern hemisphere of the photo are part of an ectopic spicule. Examination of topotype material collected by the first author confirms that the type species is attributable to Secuicollacta .
