A stunning example of an ammonite fossil of the species Xipheroceras planicosta from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of limestone matrix measures 78 mm (3.1 inches) across and the fossil ammonite measures 35 mm (1.4 inches). The ammonite is very well preserved and has been prepared out of the rock to reveal the whole shell. The ribs are very finely defined, and the dark brown colour is beautiful.
A great example of the species and impressive in the flesh. The fossil weighs 190 grams and has cut flat bases 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.
