One of my favourite spots to fossil hunt in Birmingham city
centre. This
building is brick built but clad in limestone, which was quarried on Anglesey,
north Wales, at a place called Penmon. The rock is Penmon Limestone and is full
of marine fossils including corals and shells. The corals are really quite
spectacular. These fossils are Carboniferous in age, so are around 350 million
years old.
