What is it?
The fossilised stump of a tree that grew in the Carboniferous forest 320 million years ago. It is a species known as Sigillaria which could grow to a height of 30 metres and is an early ancestor of modern clubmosses which today are small mountain plants. When the original tree died the stump was buried and sand from a nearby river filled the space left by the rotting wood and eventually hardened forming a large sandstone fossil.

What is its relevance to the North Pennines?
The Stanhope tree was discovered in a sandstone quarry at Edmundbyers Cross in 1915 and is one of several that have been discovered in this area. It was brought to Stanhope in large pieces in the early 1960s where it was reassembled and put on display in a quiet corner of the churchyard adjacent to the Market Square where it now features as a tourist attraction.

Why is it important?
The Stanhope Fossil Tree is a remarkable survivor from the distant Carboniferous era when the piece of the earth’s crust that would eventually become the North Pennines lay close to the equator covered by rainforests and fringed by shallow, tropical seas. The Carboniferous forests contained some of the earliest land plants of which this fossilised remnant is an amazing example.
