Meschedea Won, 1983

Meschedea Won, 1983: 154 .

TYPE SPECIES. — Meschedea pyramispinosa Won, 1983 ( Won 1983: 154, pl. 4, fig. 5-7).

AGE AND LOCATION OF TYPE MATERIAL. — Lower Carboniferous, Rheinischen Schiefergebirge, Germany.

TAXON CODE. — 101.

STATUS. —Junior synonym of Pluristratoentactinia Nazarov,1981 (herein).

DIAGNOSIS. — “Das sphäroidale Skelett besteht aus 3 Schalen, die von einem Gitterwerk gebildet werden. Der Abstand zwischen den beiden äusseren Schalen ist geringer als der zwischen der mittleren Schale und der innersten Schale. Die Oberfläche des Skeletts weist zahlreiche, kleine, runde, dichtstehende Poren auf. Die 3 Schalen sind durch innere Stacheln und zahlreiche Dornen miteinander verbunden. Die Stachelzahl auf der Oberfläche variiert. Im Vergleich zu anderen Gattungen ist der Durchmesser der innersten Schale im Verhältnis zur Skelettgrösse recht gross.“ ( Won 1983: 154).

DIAGNOSIS (English translation by J. P. Caulet – RadWorld database – modified by Jörg Maletz). — Spherical test with three lattice shells. The interval between the two external shells is smaller than the interval between the median and medullary shells. Surface of the shell with many small, circular, closely distributed pores. The three shells are linked by internal spines and numerous thorns. Number of external spines variable. Compared to other genera, the diameter of the medullary shell, related to the size of the test, is very large.
