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 51 mm (2 inches) across and the fossil ammonite measures 20 mm (0.78 inches) across. 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 dark grey and yellow colours are beautiful. This one is unusual as it 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 110 grams.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
