5″ GOODHALLITES GOODHALLI Ammonite Fossil Cretaceous Albian Texas USA

£43.20

Offered here is a superb 5″ specimen of Goodhallites goodhalli, a rare ammonite species from the Duck Creek Formation of Spring Creek, Cooke County, Texas, USA. This ammonite dates to the Upper Albian stage of the Cretaceous period—approximately 105 to 100 million years ago—when North America’s Western Interior Seaway teemed with marine life.

Goodhallites goodhalli is a member of the family Brancoceratidae and superfamily Acanthoceratoidea. These ammonites are known for their relatively evolute shells with bold, coarse ribbing and subtle tuberculation. The fossil reflects high preservation detail with pronounced growth lines and well-defined ornamentation that make it ideal for display or study.

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.
