| Abstract: | Phosphatic structures are discovered in the tube interior of the hyolithelminth species Hyolithellus vitricus from the Lower Cambrian of the Siberian Platform. Anatomic interpretation of these structures suggests that these small-sized shelly fossils represent the earliest worm-shaped organisms probably closely related to modern Nemathelminthes. |
