The upper lias is for many collectors a firm favourite. There is a bit of a problem with some of the ammonites on the “wants list”, especially the Dactylioceras genus : Many of those have been described by the great Sydney Savoury Buckman, in his “Yorkshire Type Ammonites” – but not many times afterwards. So some of these may not be “real” species…
What do you do if you think you have one of the ammonites on the list ?
Simple : Post a comment in the specific post (you have to leave your e-mail address but noone else but me can see it) and I will contact you !
So here´s the upper lias list : Some of these are real rarities, some may not even occur in Yorkshire, but please surprise me !
