I believe this to be dactylioceras ammonite fossil from the UK's Jurassic coast.  Positive and negative is included in your  order. These are very old, millions of years old. This was sold to me by another vendor who did not have the information on this purchase. I have researched and this is what I have found out about these speciments.  You will received this actual fossil. I am not certain of the origin, but this would be cool to add to anyone collection.
