Pugnoides is a fairly typical, coarsely-ribbed, rhynchonellid, one of the most distinctive brachiopod groups. Rhynchonellids first appeared in the early Ordovician (more than 470 million years ago) and are still one of the two dominant groups alive today, the other group being the smooth-shelled terebratulids.
