Excellent specimen! I don't know the exact species of Mort., the sources are confusing.
ReplyDeleteMy name is Lori Ferguson, I have two fossils just like the one you call Mort. Ammonite. They are big as a basket ball. My husband brought them home to me from an Oil Rig near Odessa Texas about three years ago. Cool to now know what they are.
