    Cover: Scallops of the Upper El Molino Formation leading to the deep red Santa Lucia Formation in the Maragua syncline southwest of Sucre, Bolivia. Alternation between carbonate and siliciclastic lithologies form each scallop, recording a period oscillation in water depth of the Late Cretaceous–Early Paleogene Potosi Basin driven by orbital forcing. See “Astronomically forced hydrology of the Late Cretaceous subtropical Potosí Basin, Bolivia” by Tasistro-Hart et al., p. 1931–1952.
