Genus NODOSARCHAEDISCUS

NODOSARCHAEDISCUS Conil and Pirlet, 1974
Type species: Archaediscus maximus Grozdilova and Lebedeva, 1954 (*1321), p. 51; OD.
Nodosarchaediscus Conil and Pirlet, in Pirlet and Conil, 1974 (*2411), p. 264.
Test discoidal, proloculus followed by well-developed early coil, with whorls aligned, sigmoidal or oscillating, lacking a central stel­late area but with rounded to angular nodosities filling most of the chamber lumen; wall with inner dark wall layer entirely covered by the radial layer throughout the test. Carbonifer­ous (L. to M. Visean); W. Europe; USSR; Iran; North America.
 
Remarks: Although regarded as a syno­nym of Lensarchaediscus by Zaninetti and Altiner (1979, *3429), Nodosarchaediscus has some openings remaining in the chamber lumen, whereas the original illustration of the holotype of Lensarchaediscus shows a completely occluded chamber as in typical Asteroarchaediscus. Thus Nodosarchaediscus is recognized as distinct.
