Asteroceras confusum Spath.XX N.B RESERVED FOR P.D. XXX
Fine complete specimen to center one side. The last part of the body chamber shows open crystal filled chambers. In several areas a very strange from of mineralization is evident consisting of circular 'masses'. This very much resembles 'Beekite' which can form when silicification occurs. I have never seen this particular occurrence ever in any Lyme Ammonites.
Jurassic, Upper Sinemurian, Obtusum Zone.
Black Ven, Lyme Regis / Charmouth, Dorset.
7.2 cm. diam.
