A stunning example of an ammonite fossil of the species Xipheroceras planicosta from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The two pieces of limestone matrix each measure 112 mm (4.5 inches) across and the fossil ammonite measures 31 mm (1.22 inches). The rock has been split to perfectly reveal the positive and negative parts of the ammonite, which can be put back together or displayed separately. The ammonite is very well preserved and has been prepared out of the rock to reveal the shell. The ribs are finely defined, and the dark brown colour is beautiful.
A great example of the species and impressive in the flesh. The two pieces together weigh 1065 grams and have cut flat bases to allow them to stand freely for display.
Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
