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 155 mm (6.1 inches) across and the fossil ammonite measures 26 mm (1 inch). The ammonite is very well preserved and has been prepared out of the rock to reveal the shell. The ribs are finely defined, and the mixed grey and mottled brown colour 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 fossil weighs 505 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.
