摘要:
Cervids of the Forest Bed Formation were studied by the present author in a paper now 40 years old. Some identifications and generic attributions are here revised. The fossils fall into one, or possibly two, distinct levels of the late Villefranchian (Early Pleistocene) and in the earlier Middle Pleistocene (Galerian, =Cromerian). In the earlier paper four elk species were recognized; these are now reduced to two:Cewalces gallicus, from the younger Late Villefranchian, andCewalces latifrons, from the Galerian. A skull from Mundesley is proposed as the neotype of the latter, to replace a poorly diagnostic original holotype. These species are not closely related to the livingAlces alcesbut are forerunners of the North AmericanCewalces scotti.The phylogeny of Pleistocene elks is discussed in this context. Giant deer are represented by two genera, with three species:Megaceroides verticomis, Megaceroides dawkinsiandMegaloceros savini.Some fossils misinterpreted in the former paper are revised.Megaceroides dawkinsiseems to be endemic to Great Britain, raising an intriguing problem of palaeogeography.
