In siderite concretions from the (now closed) opencast mine Crockhey
between Manchester and Liverpool beautifully preserved plant fossils as well
as animal fossils have been found. In the quarry coal has been mined, dating
from the Upper Carboniferous (Westphalian A). Siderite is an iron compound
which is sometimes used as ore.
Below are six extremely fine specimens of the extinct horseshoe crab
Euproops rotundatus. Click on the photos for enlargement.
The pictured fossils are from the collections of Andrew Tenny (Smithybridge)
and Lee Cherry (Reddish, Stockport).
