The Coon Creek Formation is a geologic formation located in western Tennessee and extreme northeast Mississippi. It is a sedimentary sandy marl deposit, Late Cretaceous (Maastrichtian) in age, about 70 million years old. The formation is known for producing mosasaurs and plesiosaurs, particularly at Coon Creek in McNairy County, Tennessee, which the formation is named for. Additionally, the formation produces many other marine invertebrates such as Turritella and the state fossil of Tennessee, the bivalve Pterotrigonia thoracica, as well as other fossils such as crabs.

Famous quotes containing the words creek and/or formation:
“It might be seen by what tenure men held the earth. The smallest stream is mediterranean sea, a smaller ocean creek within the land, where men may steer by their farm bounds and cottage lights. For my own part, but for the geographers, I should hardly have known how large a portion of our globe is water, my life has chiefly passed within so deep a cove. Yet I have sometimes ventured as far as to the mouth of my Snug Harbor.”
—Henry David Thoreau (1817–1862)
“I want you to consider this distinction as you go forward in life. Being male is not enough; being a man is a right to be earned and an honor to be cherished. I cannot tell you how to earn that right or deserve that honor. . . but I can tell you that the formation of your manhood must be a conscious act governed by the highest vision of the man you want to be.”
—Kent Nerburn (20th century)
