Article: Wealden mammalian fossils
Only two of the previous identifications of specimens considered to be teeth of Wealden mammals can be accepted without reservation. A special collecting technique including both chemical and mechanical processes facilitated the discovery of eight more Wealden mammalian fossils. Five were found in the Cliff End Bone Bed, a part of the Ashdown Beds, and the remainder in the Paddockhurst Bone Bed, a part of the Grinstead Clay. These fossils give additional information about the morphology of the multituberculate Loxaulax valdensis and demonstrate the presence of a symmetrodont and eupantothere in England in the early (pre-Aptian) Cretaceous.
