Fossils of these tyrannosaurs can be found in the Judith River Formation in Montana and the Formations in Alberta. All tyrannosaurs are related and are early relatives of the Tyrannosaurus rex, which appeared at the end of the Cretaceous Period. All three of these tyrannosaurs are smaller than Tyrannosaurus rex. The Daspletosaurus and Gorgosaurus were similarly sized and lived together during the same time. They are approximately 30 feet long and weigh up to 5000 lbs. Albertosaurus had a similar length of up to 30 feet but was lighter, with a maximum weight of 4000 pounds. Albertosaurus appears to have evolved slightly later than its two Judith River Formation tyrannosaur relatives\u003c\/p\u003e\n\u003cp\u003eTeeth from Albertosaurus, Daspletosaurus, and Gorgosaurus share similar dimensions and morphology, rendering the identification of isolated specimens highly challenging. Daspletosaurus, somewhat larger than the other two tyrannosaurs and belonging to the same subfamily as Tyrannosaurus rex, likely possessed dental features more closely aligned with T. rex. In contrast, Albertosaurus teeth tend to be smaller and more slender, adapted primarily for slicing prey. These exquisite Late Cretaceous tyrannosaur teeth from northern North America exemplify exceptional preservation and represent noteworthy early relatives of Tyrannosaurus rex.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/Albertosaurusfinalimage_1024x1024_1_480x480.webp?v=1691687895\" width=\"776\" height=\"388\"\u003e\u003c\/p\u003e\n\u003chr\u003e","brand":"MT 2500","offers":[{"title":"Default Title","offer_id":52441721209112,"sku":"06JZZ786","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/5U8A8972_a7889ce7-bd0d-4350-93dd-1e6c73e52c2a.jpg?v=1785014369","url":"https:\/\/www.fossilageminerals.com\/products\/0-7-tyrannosaur-fossil-tooth-cretaceous-dinosaur-judith-river-fm-mt-coa-display-06jzz786","provider":"Fossil Age Minerals","version":"1.0","type":"link"}
