The Manitou Limestone is a geologic formation in Colorado. It preserves fossils dating back to the Ordovician period.
Depositional Environment
[edit | edit source]Because the rocks of the Manitou Dolomites are mostly indeterminate carbonates, the exact depositional environment is unknown. However it was likely shallow water, either lagoon or near-shore, and the many jumbled fossils of trilobite spines and brachiopods suggest that the paleoenvironment may have been prone to storms.
Paleontology
[edit | edit source]The limestones and dolomites of the Manitou Formation, contain cast/mold-preserved Ordovician-aged marine fossils, including cystoid stems, brachiopods, and trilobites such as Manitouella (Leiostegium?) and Kainella.
