A stunning example of an ammonite fossil of the species Xipheroceras dudressieri from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of limestone matrix measures 195 mm (7.68 inches) across and the fossil ammonite measures 50 mm (1.9 inches) across, which is a good size for this species. The ammonite is very well preserved and has been prepared out of the rock to reveal the whole shell. This species has a distinctive row of spines on the outer whorl, which are nicely displayed in this specimen. The ribs are very finely defined, and the colour is beautiful: a deep chocolate brown. A great example of the species and impressive in the flesh. The fossil weighs 1305 grams and has a cut flat base to allow it to stand freely on its own for display.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
