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
Cardium
striatulum
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 :
Montinaltia
Rhynochonella

From the Oxford Clay:
