A stunning example of an ammonite fossil of the species Promicroceras planicosta from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
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 with a surprise inside!
The limestone matrix measures 78mm (3.1 inches) tall and contains one and a half ammonites, which are very well preserved and have been prepared out of the rock to reveal the shells. The complete ammonite measures 26mm (1 inch) across. The ribs are very finely defined, and the mix of yellow, brown, and grey colours is beautiful. A great example of the species and impressive in the flesh.
These calcite ammonites make great unique gifts for the nature lover in your life! The combined weight of the two pieces is 122 grams.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
