A stunning and unusual example of an ammonite fossil of the species Xipheroceras planicosta from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.

The piece of limestone matrix measures 65 mm (2.5 inches) across and the fossil ammonite measures 35 mm (1.4 inches). The ammonite is very well preserved and has been prepared out of the rock to reveal the shell. It is a very unusual example as there is a geological fault line running through the rock that cuts through the ammonite. This has led to part of the shell being deformed away from the rest of the shell. this would have happened over millions of years as the earth slowly moved until the rock split and then recrystalised. The ribs are finely defined, and the mixed brown colour is beautiful. A very unique example with a story to tell!

A great example of the species and impressive in the flesh. The fossil weighs 262 grams and has a cut flat base to allow it to stand freely for display.

Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
