A stunning example of an ammonite fossil of the species Promicroceras planicosta from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The main piece of limestone matrix measures 45 mm (1.75 inches) across and the fossil ammonite measures 22 mm (0.85 inches) across. 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 brown and yellow colours are beautiful. This one is very unique as it also has a small bite mark in the outer whorl that would have been made by a predator that killed and ate the ammonite. A great example of the species and impressive in the flesh. The fossil weighs 25 grams (both pieces combined).
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
