A stunning example of an ammonite fossil of the species Xipheroceras planicosta from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The ammonite, which measures 37 mm (1.48 inches) across, sits in one of two pieces of limestone matrix, the largest of which measures 96 mm (3.76 inches) wide. This is a classic "popped" stone, where the rock has been split to reveal both the positive cast of the shell and the negative impression. The two pieces fit back together and can be displayed separately or as a single piece with a surprise inside! The ammonite is very well preserved and has been prepared out of the rock to reveal the shell. The ribs are very finely defined, and the light yellow and dark grey colours are beautiful. A great example of the species and impressive in the flesh. Both pieces of matrix together weigh 295 grams.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
