« backJURASSIC FOSSILISED LOG
Showing knot holes
190 million years old
Charmouth, near Lyme Regis, Dorset
An impressive compressed log of fossilised wood from the Black Ven Mudstone of the Lower Lias. These rocks were laid down as mud on the floor of a tropical sea in Lower Jurassic times and the presence of these logs demonstrates that land was not far away and it supported a coniferous forest. Flowering plants had not yet evolved.This is effectively a piece of driftwood from the nearby rainforest that was swept out to sea to settle on the sea floor.
