AbstractMyzostomida comprise a taxon of mainly soft-bodied, flattened, oval, and disc-like marine protostomes. They are usually associated with echinoderms. Most myzostomids exhibit five pairs of uniramous parapodia comprising aciculae and hooked setae, but a distinct head, pygidium, or signs of external segmentation are lacking.

The phylum of segmented worms (Annelida) contains truly metameric animals. Their body consists of similar ‘rings’ that are alike not only concerning their appearance but also their inner structure. The epithelium of annelids composes a functional unit together with the muscle fibres beneath.

The rocks with the worm passages in Donbas were known previously in the deposits of the upper carbon, in limestones and marls of araucarite thickness. For the last years the typical ??worm) layers of regional distribution and quite definite stratigraphical position are found in the deposits of low carbon in the West Donbas. They are met in the deposits

Annelida are typically characterized by the presence of segmentation and can be found in all habitats on the Earth. Traditionally regarded as being closely related to arthropods, with several very well-known toxic or venomous species, molecular data robustly placed them within Lophotrochozoa. Besides annelids, only one other taxon within Lophotrochozoa,
