A stunning example of a calcite ammonite fossil of the species Asteroceras obtusum from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of limestone matrix measures 97 mm (3.45 inches) tall and the fossil ammonite measures 43 mm (1.7 inches) across. The ammonite is well preserved and has been prepared out of the rock to reveal the whole shell. The ribs are very finely defined, and the colour is beautiful: deep brown with pale suture lines, which are very well defined on this one.
A great example of a popular species and impressive in the flesh. The fossil weighs 140 grams and a cut flat base to allow it to stand freely on its own for display. Fossils like this make great display pieces and add a real focal interest to any shelf, not to mention being a great conversation piece!
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
