A stunning example of a highly pyritised ammonite fossil of the species Oxynoticeras lymense from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The fossil measures 62 mm (2.45 inches) across, which is large for this species. The ammonite is very well preserved on both sides with some of the original shell still preserved on top of the iron pyrite, which is unusual in this species. The shell has nice detail in the suture lines and ribbing and the metallic colour and shine is beautiful. There are also some bivalve shells attached to the side of the shell, which would have been attached to the shell on the seafloor before it fossilised. A great example of the species. Incredible in the flesh. These ammonites are becoming much harder to find these days due to lack of erosion of the right layers of rock. The fossil weighs 115 grams.
Around 196 million years old, this fossil would make a wonderful addition to any collection
