Janulum sp.

Fig. 5B–D.

Material.—Middle Eocene, south-central Ukraine.

Remarks. —The strongyles ( Fig. 5B–D) are similar in size (165–250 μm) and morphology to acanthostrongyles of the modern raspailiid genus Janulum (compare Kelly et al. 2015: figs. 2, 3). The fossil spicules seem to have some signs of erosion in places where the spines in the modern spicules originate.
