A stunning example of a highly pyritised ammonite fossil of the species Eoderoceras (Eteoderoceras) armatum from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.
The limestone matrix measures 200 mm (7.87 inches) across and the fossil ammonite measures 92 mm (3.6 inches) across, which is large for this species. The ammonite still sits in the original shale in which is was found. This is rare to see with this species as it is preserved in fragile shale that usually falls apart when it dries out. This example however has been stabilised and the shale consolidated to make it strong and very stable. This makes it a wonderfully unique display piece. The ammonite is beautifully preserved within the shale. The ribs are very finely defined, the suture lines are detailed, and the golden metallic colour and shine is beautiful. There are also other ammonites that are preserved compressed within the shale. The shale has a cut-flat base to allow it to stand freely on its own for display. This looks great on the mantelpiece! A great and rare example of the species. These ammonites are becoming harder to find these days and this one is a real one-off specimen A heavy fossil, weighing 1755 grams.
Around 196 million years old, this fossil would make a wonderful addition to any collection.
