Several of these "teeth" were found together - Jack Doyle suggests they are "ventro-lateral spines from the large ammonite, Endemoceras sp, The nacreous lustre is, I believe, the give-away.

At the base of the spine, you may find a characteristic concavity, representing a line of weakness at which the spines break away from the main shell. "
