Period: Neogene Epoch: Early Miocene to Middle Miocene Faunal stage: Aqitanian ~18.9 to 18.3 mya, calculates to a period of 0.6 million years The Chipola Formation is found along the Chipola River.

The coloration is from cream to olive gray with mottled reddish brown in the weathered sections.

The sands are soft and very fine to coarse with sporadic gravel while carbonate lenses are quite hard.

[1] The Chipola Formation of the Early Miocene contains one of the most diverse, high-abundance ecosystems of mollusks ever described.
