This herbivorous species is distinguished by its large body, strong legs, and three prominent facial horns - one on the nose and one above each eye. The most striking feature of Triceratops is its large skull, which includes a solid frill at the back. This frill, combined with the horns, was likely used for defense against predators, such as Tyrannosaurus rex , as well as for display and species recognition among other Triceratops. Fossil evidence indicates that these dinosaurs could grow up to 30 feet in length and weigh between 6 to 12 tons. Their teeth were arranged in groups that formed a constantly replaced battery, ideal for their diet of fibrous plants. Triceratops fossils are among the most abundant for any dinosaur, making it a key species for understanding the Late Cretaceous period.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Fossils Online","offers":[{"title":"Default Title","offer_id":63483870740620,"sku":null,"price":8700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/3697\/5500\/files\/DISP-11.jpg?v=1792793473","url":"https:\/\/fossilsonline.com\/products\/triceratops-squamosal-with-epoccipitals-lance-formation-wyoming","provider":"Fossils Online","version":"1.0","type":"link"}
