Notes on some Late Cretaceous goniasterid starfish (Echinodermata, Asteroidea) from Belgium and Germany

Both partially articulated specimens and dissociated marginal ossicles form the basis for erection of two new species Late Cretaceous goniasterids from Mons Liège-Limburg basins (Belgium) Hannover area (Germany). Chomataster breizh sp. nov., which recalls type species, acules Spencer, 1913, but differs in several respects, is based on a partial external mould frame disc arms flint (upper Campanian Spiennes Chalk Formation; Basin), as well more or less complete individual, preserving small, spherical spines granules encased nodule upper Maastrichtian Nekum Member (Maastricht Basin). In Ch. supero- inferomarginals bear close-set granule pits, varying sizes, bivalved alveolar scars pedicellariae; median superomarginals all lack large, crater-shaped spine pits – such are found only disc/arm transition along arms. Dissociated inferomarginal lower northeast Belgium, previously recorded either indeterminate astropectinids Nymphaster obtusus (Forbes, 1848) var. nov. sp., respectively, here assigned to mudzborgh This characterised by row 3–5 large aboral lateral surfaces superomarginals; have an angular profile close cover pits. tethysiensis Villier, 2001, Landes (southwest France; Villier Odin, 2001) appears best accommodated well, because arm alternate rather than meet over mid-radial line.
