卖家的描述
Scientific name: Phytosaur - 半水生爬行动物牙
Location: Navajo County, Arizona, USA. Private land.
Geological Formation: Chinle Fm
Age: Late Triassic, Norian–Rhaetian stage ( ~ 227.3 to 201.4 million years)
Size: 3.8 cm
REF.: #J603
DESCRIPTION:
Stunning massive gem grade phytosaur tooth from the Chinle Formation in Navajo County, Arizona, is a Late Triassic reptile. These teeth typically feature sharp serrations, and belong to large, crocodile-like aquatic predators.
Fossil Features and ContextAge: Late Triassic period.
Location: Navajo County, Arizona (within the extensive Chinle Formation rock layer).
Creature: Phytosaurs were large, meat-eating reptiles that looked like modern crocodiles but evolved separately.
Size: Common teeth measure about 1 to 1.5 inches, though rare specimens can exceed 2 inches and may belong to large genera like Smilosuchus.
Identification: Specimens feature curved, conical shapes with fine serrated edges (carinae) along the sides, adapted for holding slippery prey in ancient river and swamp ecosystems. Opinions are mixed when identifying isolated fragments, as wear can make it hard to tell sharp ridges apart from true serrations.
All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Display box included.
