The Mooreville Chalk Formation is a geological formation in North America, within the U.S. states of Alabama and Mississippi. The strata date back to the early Santonian to the early Campanian stage of the Late Cretaceous. The chalk was formed by pelagic sediments deposited along the eastern edge of the Mississippi embayment. It is a unit of the Selma Group and consists of the upper Arcola Limestone Member and an unnamed lower member. Dinosaur, mosasaur, and primitive bird remains are among the fossils that have been recovered from the Mooreville Chalk Formation.

Famous quotes containing the words chalk and/or formation:
“Through throats where many rivers meet, the curlews cry,
Under the conceiving moon, on the high chalk hill,
And there this night I walk in the white giant’s thigh
Where barrren as boulders women lie longing still
To labour and love though they lay down long ago.”
—Dylan Thomas (1914–1953)
“It is because the body is a machine that education is possible. Education is the formation of habits, a superinducing of an artificial organisation upon the natural organisation of the body.”
—Thomas Henry Huxley (1825–1895)
