Fossil Shark Tooth – Ptychodus anonymus, Arcadia Park Formation, Upper Cretaceous, The Colony, Texas, USA – 100% Genuine with COA
£24.00
This Fossil Shark Tooth belongs to the species Ptychodus anonymus, an ancient shark that lived during the Upper Cretaceous Period. The tooth was found in the Arcadia Park Formation, part of the Kamp Ranch Member in The Colony, Texas, USA. The Ptychodus anonymus was a durophagous shark, meaning it primarily fed on hard-shelled prey such as mollusks, which is evident from the morphology of its teeth.
Geological Information:
Geological Stage: Upper Cretaceous (Approximately 100 to 66 million years ago)
Depositional Environment: The Arcadia Park Formation was formed in shallow marine environments during the Cretaceous period. This formation was a warm, shallow sea that covered much of what is now the United States, and it supported a diverse ecosystem of marine life, including sharks, mollusks, and other sea creatures.
Biozone: The Arcadia Park Formation is known for its rich fossil deposits from the Upper Cretaceous, particularly from species like Ptychodus anonymus, which was common in the Western Interior Seaway.
Fossil Features:
Family: Ptychodontidae (A family of durophagous sharks)
Super Family: Ptychodontoidea (Group of sharks with specialized teeth for crushing hard-shelled prey)
Order: Carcharhiniformes (Common shark order)
Morphology: The Ptychodus anonymus tooth features a flat, wide crown with a broad base, which was ideal for crushing hard-shelled organisms like mollusks. The tooth’s shape and structure are key indicators of its specialized diet, distinguishing it from the more typical sharp-edged teeth of predatory sharks.

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.
