"The Upper and Lower Writhlington, Huish & Foxcote were all merged into one colliery." Obviously the "&" is a MoS no-no, so was the name of the colliery "Huish & Foxcote"?
Hopefully resolved.

"The spoil heap is a now Writhlington Site of Special Scientific Interest, and includes 3,000 tons of Upper Carboniferous spoil from which more than 1,400 insect fossil specimens have been recovered, including Phalangiotarbi,[10] and Graeophonus.[11] and the world's earliest known Damselfly,[12] It is a Geological Conservation - Protected Site." There are a few things wrong with this sentence, apart from its attempt on the world length record. Why "fossil specimens" rather that just "fossils"? Is the bit following "Damselfly" meant to be a new sentence? Is " Geological Conservation - Protected Site" an official designation? Whether it is or not, there's a problem with that hyphen. Should it be some kind of dash?
Hopefully resolved.
