Palacantholithus Deflandre, 1973b: 499 ; 1973a (nomen nudum).

TYPE SPECIES. — Palacantholithus stellatus Deflandre, 1973 ( Deflandre 1973a: 291, pl. 3, fig. 2-6, pl. 4, fig. 8).

AGE AND LOCATION OF TYPE MATERIAL. — Visean, Cabrières, Hérault, Montagne Noire, France.

TAXON CODE. — 040.

STATUS. — Valid.

DIAGNOSIS. — Spicule siliceux avec une courte actine axiale perpendiculaire à une zone centrale de laquelle partent dans un même plan n actines qui se recourbent ensuite dans le même sens, à l’instar des baleines d’un parapluie; actines cylindriques, simples ou avec des épines ( Deflandre 1973b: 499).

DIAGNOSIS (English translation by J. P. Caulet – RadWorld database). — “Siliceous spicule with a short axial spine perpendicular to a central area from which are issued in the same plane n spines that are curved in the same direction, as the ribs of an umbrella; spines cylindrical, simple, or with small thorns.”

REMARKS

Re-examination of the holotype from Deflandre’s collection shows that it is a spicule with rays disposed in the three Cartesian axes (one ray completely broken off) suggesting that it is a spicule of Haplentactinia type.
