The plaque reads: "The fossil was uncovered in 1889 in sandstone quarries at Clayton near Bradford. This stump and roots (called Stigmaria) are all that remain of a giant tree. It grew in forests in Carboniferous times, 330 million years ago. Yorkshire was a hot, steamy tropical swamp near the Equator. The tree was 40 metres high. Can you see its huge spreading roots? During a flood the trunk was snapped off. The decaying hollow stump filled up with sand. The outer wood layers became coal. Over millions of years the sand hardened into sandstone rock. The tree stump became a fossil."
