Cover Story: The yellow-green luminescence of fossil gastropod shells in a siderite concretion in the Early Cretaceous McMurray Formation of northern Alberta Canada shows that the crossed-lamellar microstructure of the nacreous layer of these shells retains the original aragonite mineralogy.  The exceptional preservation of these fossil shells and associated authigenic carbonates allows for stable isotopic characterization of the ancient river system that deposited the sediments of this part of the McMurray Formation. The results indicate that the drainage basin of this river system extended over much of the North American continent during the Early Cretaceous. This conclusion is compatible with results from other studies on sediment routing during deposition of the McMurray Formation. View this paper
