What makes this specimen particularly special is that these two bones (phalanx IV-3 and IV-4) were found together, meaning they almost certainly came from the same individual animal. Associated skeletal elements like this are relatively uncommon finds and offer a more complete picture of hadrosaur anatomy than isolated bones.\u003c\/p\u003e\u003cp\u003eHadrosaurs were among the most successful and abundant dinosaurs of the Late Cretaceous period, approximately 66 to 80 million years ago. These large herbivores could reach lengths of 30 feet or more and traveled in herds across the ancient floodplains, river systems, and coastal environments that would become modern-day Montana. Their robust limbs and well-developed feet supported their massive bodies as they foraged on the diverse vegetation of the Cretaceous world — sharing their environment with apex predators like \u003cem\u003eTyrannosaurus rex\u003c\/em\u003e and armored giants like \u003cem\u003eTriceratops\u003c\/em\u003e and ankylosaurs.\u003c\/p\u003e\u003cp\u003eRecovered from either the \u003cstrong\u003eJudith River Formation\u003c\/strong\u003e or \u003cstrong\u003eHell Creek Formation\u003c\/strong\u003e of Montana, this specimen represents the final chapters of the Age of Dinosaurs. Both formations are world-renowned among paleontologists for their exceptional preservation of Late Cretaceous fauna, though precise species attribution within Hadrosauridae requires more complete skeletal material for definitive identification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecimen Highlights:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Authentic associated hadrosaur phalanges — digit IV, phalanx 3 and phalanx 4 from the same individual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e IV-3 measures approximately 2.61 inches; IV-4 measures approximately 2.70 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Excellent preservation with one professionally repaired break — stable and display-ready\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProvenance:\u003c\/strong\u003e Judith River or Hell Creek Formation, Late Cretaceous (~66–80 million years ago), Montana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthenticity Guarantee:\u003c\/strong\u003e 100% genuine dinosaur fossils\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis associated pair of phalanges offers a tangible connection to the powerful limbs that once carried one of the most successful dinosaur groups across the ancient landscapes of North America.
