Location - Axmouth Undercliff, Dorset
Age - Early Jurassic (blue lias, 198 mya) unconformably overlain with a cretaceous blanket of chalk, upper greensand and gault.
The Blue Lias runs along the beach and in places is full of large ammonites and nautiloids. Very little Jurassic material is collectable.
The cretaceous blanket is present in the form of large boulders which have fallen from the overlying cliffs.
All the fossils collected were from the cretaceous. Several could be identified.
Bivalves - Amphidonte obliquatum - very common
Neithea gibbosa (probably) - from a large fragment
Ptychodus mammillaris - shell crushing shark tooth
Rotularia concava (serpulid worm)
The following need identification.
1. Shark tooth found in chalk (13 mm)
After extraction
2 Shark tooth from Gault (22 mm)
3. Coral? (6 mm)
4. Flint (38 mm) - could it be inner section of ammonite?
