Abstract

A new genus and species of plagiaulacid multituberculate (Mammalia, Allotheria, Multituberculata) is described from the Cherty Freshwater Beds, Warbarrow Tout Member of the Lower Cretaceous Lulworth Formation of the Purbeck Group, Dorset, United Kingdom. The new taxon is represented by a complete, well preserved left dentary containing the incisor, p2–4, with alveoli for m1–2. This new specimen is the most complete multituberculate material yet recovered from the Purbeck Group. It is also the first mammal to be recovered from the so-called ‘Flint Bed’ (DB97).
