Family Microcionidae Carter, 1875 View in CoL Microcionidae indet.

Fig. 6E, F, J, M View Fig .

Material.—Upper Eocene, south-central Ukraine.

Remarks. —The acanthostyles with massively sculptured heads ( Fig. 6E, F View Fig ), as well as other acanthostyles illustrated on the same figure ( Fig. 6J, M View Fig ), could be assigned to some of the microcionid genera. For instance, the former resemble the acanthostyles present in modern Clathria ( Thalysias) zeai van Soest, 2017 (compare van Soest 2017: fig. 95b, e). Similar spicules also appear in Discorhabdella Dendy, 1924 compare Boury-Esnault et al. 1994: fig. 83a).
