Genus Globulocrinus nov.
Type species. Globulocrinus amphoraformis n. gen, n. sp.; lower Ypresian .
Etymology. In reference to the basal circlet of globular feature, at least in juveniles.
Diagnosis. More or less urn- or amphora-shaped aboral cup, oblong to globular basal circlet, distinct radial circlet generally subcylindrical to slightly flare and of much smaller diameter than upper part of basal circlet; distal face of radial circlet with wide central depression and discrete interradial ridges. Brachials and columnals not yet identified.
Remark. Conocrinus globulosus Roux, 1978c is known to the Bartonian of Biarritz (Côtes des Basques) only from a small, more or less crushed aboral cup that could correspond to a juvenile specimen ( Roux et al. 2019). We prefer to designate as the type species of the genus, G. amphoraformis n. gen., n. sp., whose type series illustrates the variability and shape modifications of the aboral cup during growth.
Included species. Conocrinus globulosus Roux, 1978c and Globulocrinus amphoraformis n. gen., n. sp.
Stratigraphical distribution. Eocene (Ypresian–Bartonian).
