Fossil Arthropods from the Tyne Coalfield

Remains of arthropods are among the rarest of fossils in the Coal Measures. Rare as they are, however, they have been recorded in some numbers from nearly all the principal coalfields, including those of the British Isles, the Continent of Europe, and North America. But of the larger British coalfields, that of Northumberland and Durham appeared till recently to be conspicuously poor in fossil arthropods.
