Description

Lytoceratidae are a quite rare family of ammonites. Their shell with external ribs resembles a horn of plenty, ant its unique suture design makes this ammonite particularly attractive.
They are found mainly in Jurassic layers (191-171Mya) in France, Germany, Hungary, Portugal, Spain, Tunisia, UK and USA.
The Lytoceras had very few evolutions during his life in Jurassic. It was a fast predator of deep waters, and its rarity can be tied to this. It rarely went in shallow waters, so it is difficult to find its shell after its death.
The external ribs, characteristic of this kind of ammonite, ended in a collar like aperture that resembles a "horn of plenty". Unfortunately this characteristic is rarely preserved because of its fragility. Many times they are found already broken, and sometimes they break in the preparation. Also central ribs are fragile, and a layer of matrix is left on one side in order to reinforce it on the other side before cleaning it completely.
