Asteroceras obtusum display ammonite fossil (70 mm)

Asteroceras obtusum display ammonite fossil (70 mm)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 212 mm (8. 35 inches) across and the main fossil ammonite measures 70 mm (2. 7 inches) across. 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 colour is beautiful: pale

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 212 mm (8.35 inches) across and the main fossil ammonite measures 70 mm (2.7 inches) across. 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 colour is beautiful: pale brown with yellow mottling. 

It is unusual as there is another ammonite, of the species Promicroceras planicosta, sitting in the aperture (shell opening) of the Asteroceras. This ammonite is also well preserved and must have washed into the larger ammonite as they both lay on the Jurassic seafloor. 

A great example of a popular species and impressive in the flesh. The fossil weighs 1375 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.
