A stunning example of a double multi-ammonite fossil of the species Promicroceras planicosta from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece of limestone matrix measures 100 mm (3.96 inches) tall and the fossil ammonites measure 16 mm and 13 mm across. The ammonites are well preserved and have been prepared out of the rock to reveal the whole shells. The ribs are very finely defined, and the yellow colours are beautiful. A great example of the species and impressive in the flesh. The fossil weighs 585 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.
