Set of 3 dinosaur claw replicas - Fossil fragment - Tyrannosaurus

A spectacular lot consisting of three life-size replicas of three of the most important dinosaur lineages of the Mesozoic: carnivorous theropods, giant sauropods, and herbivorous hadrosaurids. Piece 1: Tyrannosaurus hind foot claw (16 cm) • Item: Ungual claw (distal phalanx) of the hind limb of a apex predator. It shows the characteristic curvature and grooves for securing the keratin sheath. • Geological origin: Hell Creek Formation, South Dakota, USA. • Exact period: Late Cretaceous (Maastrichtian stage, approx. 68–66 million years ago).

Piece 3: Terminal foot phalanx of Edmontosaurus (9.5 cm) • Item: Terminal bone of the foot (pes) of a duck-billed dinosaur. Exhibits a flattened, hydrodynamic morphology in the shape of a diamond-hoof, adapted to supporting tons of weight on muddy terrain. • Geological origin: Lance / Hell Creek Formations, Wyoming, USA. • Exact period: Late Cretaceous (Maastrichtian stage, approx. 68–66 million years ago).
