Classification
Remarks
Alloiteau (1958, p. 196ff.) stated that the presence of a parathecal-synapticulothecal wall was one of the generic characteristics of the genus Discosmilia Alloiteau, 1958. Therefore, based on the original description, Baron-Szabo (2002, p. 172) concluded that there was a close resemblance to the genus Sakalavicyathus. However, investigation of the type material of Discosmilia revealed the absence of a parathecal-synapticulothecal wall but the existence of a rather (parathecal-) septothecal wall. Moreover, the septal arrangement seems to correspond well with that of Deltocyathus. Therefore, the assignment to the latter genus is suggested (Baron-Szabo, 2008).
Distribution
- Australasia; Late Cretaceous
