Polished Orthoceras Fossil Slab
A striking and substantial Orthoceras fossil slab, featuring numerous beautifully preserved, straight-shelled fossil forms set within a naturally patterned dark stone matrix.
Orthoceras were extinct marine cephalopods related to modern-day squid and nautilus, and their distinctive elongated shells create the dramatic linear patterns visible throughout this piece. The fossils have been polished to reveal their contrasting creamy-grey chambers against the unpolished, rough, deep charcoal and black matrix, giving the slab a wonderfully sculptural appearance.
At approximately 25–30 cm across, this is a heavy and impressive piece that makes a striking addition to a fossil or mineral collection. Its natural variation in colour, pattern and fossil placement makes it a fascinating specimen to examine from every angle.
