Offered for sale is an impressive specimen of Oxytropidoceras adskinites, a distinctive ammonite fossil from the Duck Creek Formation, located in Spring Creek, Cooke County, Texas, USA. This fossil dates back to the Upper Albian Stage of the Cretaceous Period, approximately 105 million years ago.

All our fossils are 100% genuine specimens and include a Certificate of Authenticity. The photo displays the exact fossil you will receive. Scale cube = 1cm. Please refer to the image for complete sizing.

Geological & Scientific Information:

  • Fossil Type: Ammonite (extinct marine mollusc)
  • Species: Oxytropidoceras adskinites
  • Family: Brancoceratidae
  • Superfamily: Acanthoceratoidea
  • Order: Ammonitida
  • Geological Formation: Duck Creek Formation
  • Geological Stage: Upper Albian, Cretaceous Period
  • Location: Spring Creek, Cooke County, Texas, USA
  • Depositional Environment: Shallow marine shelf, part of the Western Interior Seaway system

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
