From Wealden and Purbeck :
Bones, teeth and scales of Iguanadon and Megalosaurus. Water-worn remains of the former reptiles are remarkably abundant, and a splendid collection exists in the Woodwardian Museum. For a description of these see Mr. Seeley's catalogue.
Endogenites erosa is recorded as occuring at Potton by Mr. Brodie.
Fragments of coniferous and cycadaceous woods are also found, and Mr. Carruthers has described in the Geol. Mag. for 1867 a pandaceous fruit taken from these beds.
From the Kimmeridge Clay :
Ammonites biplex Nucula ornata
Ammonites mutabilis Pleurotomariae
Ammonites cordatus Chemnitzia
Numerous teeth and spines of fishes are also found; see Ann.and Mag. of Nat.Hist. 3rd Series vol.xviii., and these may possibly have been derived from the K.C. Thus we find remains of Gyrodus Pycnodus, Hybodus, Asteracanthus ornatissimus and Sphaerodus gigas. All these are stated by Mr. Walker to occur in the clay at Ely.
From the Coralline Oolite :
From the Oxford Clay:
From Neocomian :
Ammonites Deshayesii Trigonia spinosa
Anclyoceras gigas Littorinae
Miscellaneous derived fossils :
Modiolae Strophodus magnus
Myacites Acrodus strophoides
