Amblypneustes species
Family: Temnopleuridae	Order: Temnopleuroida
Locality: Australia (no details)	Dimensions: 41,5 Ø x 44,5 mm
I got this specimen as Amblypneustes ovum, but I have some doubt, if this is correct. The height is greater than the diameter. Adoral three rows of pore pairs are present, but in the ambital region only the inner row is regular and the other pore pairs are more or less scattered. The ambulacra are distinctively broader than the interambulacra. The primary tubercles in the ambulacra are more irregular arranged than in Amblypneustes. Thus it could easily be a Holopneustes species or a hybrid.
