A stunning example of an ammonite fossil of the species Promicroceras planicosta and Asteroceras obtusum from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.

The piece of limestone matrix measures 225 mm (8.85 inches) across and contains three ammonites, the largest of which measures 35 mm (1.4 inches), which is about as big as this species gets. The two smaller ammonites are preserved in a bite mark taken out of the larger shell by a predator in the Jurassic seas. They washed against the large shell as it lay on the seafloor. One of the smaller ammonites is an Asteroceras juvenile, which is very rare to find. The ammonites are well preserved and has been prepared out of the rock to reveal the shells. The ribs are finely defined, and the grey and yellow colours are beautiful.

A great example of the species and impressive in the flesh. The fossil weighs 2.6 kg and has a cut flat base to allow it to stand freely for display. It is a fantastic display fossil with an interesting back story!

Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
