A stunning example of an ammonite fossil of the species Promicroceras planicosta from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The ammonite, which measures 28 mm (1.1 inches) across, sits in one of two pieces of limestone matrix that measure 180 mm (3.85 inches) tall . 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 shape of the pieces of rock make them great display pieces and they would serve beautifully as unique bookends. 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 colour is beautiful. A great example of the species and impressive in the flesh. The limestone pieces also have some nice white calcite "dogtooth" crystals that have grown on the edges, adding to the uniqueness of this piece. The combined weight of the two pieces is 2 kg and both have a cut flat bases to allow it them stand freely on their own for display.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
