A stunning example of an ammonite fossil of the species Promicroceras planicosta from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of limestone matrix measures 92 mm (3.65 inches) across and contains two small ammonites. The ammonites are well preserved and has been prepared out of the rock to reveal the shells. The ribs are finely defined, and the dark brown colours are beautiful.
A great example of the species and impressive in the flesh. The fossil weighs 215 grams and has a cut flat base to allow it to stand freely for display.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
