Attached is a picture of a tooth I found in the 100mya clays at Folkestone in Kent (UK). I suspect it might be some form of marine reptile, though I do not think it is conical enough. Another option might be that it is from some form of marine crocodile. It is beautifully preserved, even down to the enamel and is just over 1.5 inches long. There are no serrated edges to the tooth though it does have two slight ridges extending from the root to the tip. Any help in identifying this tooth would be appreciated. Cheers!
