what numillite-like Eocene FOSSILS IN LIKE LIMESTONE IN NORTH DAKOTA

Nummulite id - Fossil ID - The Fossil Forum

Nummulite-like Eocene fossil limestone has not been documented in North Dakota's geologic record, despite the state hosting well-documented

Eocene Vertebrates

in the Golden Valley Formation. North Dakota's Eocene deposits consist of fluvial and lacustrine sediments representing warm, humid, swampy lowlands—paleoenvironments fundamentally incompatible with the shallow marine shelf settings required for nummulite accumulation. Nummulites are

common in Eocene

to Miocene marine rocks around the Mediterranean and southwest Asia, particularly in the Tethys Ocean basin, making their absence from North Dakota geologically significant.

Are there any Eocene-aged fossiliferous limestone formations in North Dakota?

🦴 North Dakota's Eocene Vertebrate Record

North Dakota's

Eocene Vertebrates

fossil assemblages reflect continental, not marine, paleoenvironments. The Golden Valley Formation of western North Dakota preserves a diverse early Eocene fauna within riparian and aquatic settings incompatible with nummulite ecology.

• Golden Valley Formation —

  Fish, amphibians, reptiles

  , birds, and mammals recovered from early Eocene strata indicate warm, humid, swampy lowlands with subtropical forests bordering sluggish streams

• Slim Buttes Formation —

  Late Eocene age

  deposits with vertebrate fossils and large paleosol development indicate fluvial deposition in a subtropical climate with permanent streams in lowlands

• Montmorillonite content — Clay minerals in the Golden Valley may represent

  ash from volcanoes

  to the west, confirming tectonically active terrestrial setting

🌍 Why Nummulites Cannot Occur in North Dakota Eocene Rocks

Nummulites are

lens-shaped foraminifers

that were particularly prominent during the Eocene Epoch and lived exclusively in marine environments. Their complete absence from North Dakota's Eocene strata reflects the state's position on the interior North American craton, far from Tethyan marine basins.

• Geographic restriction —

  Nummulites were particularly prominent

  in limestone of the Sahara and Mediterranean regions during the Eocene Epoch; no Tethyan seaway penetrated the North American interior

• Ecological requirement — Nummulites required shallow marine shelf and platform settings with open ocean connectivity; North Dakota's Eocene basins were isolated continental depressions with freshwater and fluvial conditions

• Index fossil utility — Because nummulites are

  very abundant, easy to recognize

  , and lived in specific biozones, they are used as guide fossils—but only in marine sequences absent from North Dakota

📚 North Dakota's Actual Eocene & Cretaceous Fossil Record

North Dakota's documented Eocene and Cretaceous fossils reflect continental and coastal depositional settings distinct from nummulitic marine limestone. The state's rockhounding and paleontological heritage centers on terrestrial and marginal marine deposits.

• Fox Hills Formation —

  Trace burrows

  and petrified wood occur in this Late Cretaceous–Paleocene formation; Ophiomorpha burrows are abundant in the Timber Lake Member and become scarce in the Iron Lightning Member

• Rockhounding minerals —

  Agate, jasper, chalcedony

  and petrified wood are commonly found along major rivers including the Yellowstone, Missouri, and Cannonball Rivers, reflecting Quaternary and Tertiary depositional systems

• State fossil —

  Teredo Petrified Wood

  represents fossilized trees and tiny clams, reflecting marine-influenced coastal paleoenvironments from ancient seas

Nummulite limestone is restricted to Paleogene marine basins in North Africa and the Mediterranean, making North Dakota's continental Eocene geology fundamentally incompatible with nummulite fossil occurrence.
