The wood was in a slipped block at the southerly end of Middle Cliff along with some Hibolites – so C beds? Are the slipped blocks on the beach from the C beds? – Am I right in thinking that the faulted section marks the B/C bed boundary?. If this is the case I may need to review some of my location data – particularly the large belemnite ?Aulacoteuthis? which I suspect is then C beds, not B beds. BTW I’m still not convinced about the ID of this belemnite (see previous postings and images). I have subsequently collected a textbook Aulacoteuthis ernsti definitely from the C beds and my larger specimen looks rather different to this, notably in its size. Its proportions are rather like Oxyteuthis except for the pronounced rostral groove. Have you any specimens identified as Oxyteuthis which have a rostral groove?

I really need to get hold of the definitive papers on Speeton. I wonder as an ex Hull University postgraduate I have reading rights in the University Library?

REPLY - there are some pictures on page 398 of Shrock and Twenhofel -
but the best place to look would be the "The Treatise".

Which beds did you find them in?
