This is an authentic fragment from a rib of Allosaurus, one of the most iconic theropod dinosaurs of the Late Jurassic.

Allosaurus was a large carnivorous dinosaur and apex predator famous for its powerful build, strong S-shaped neck, and serrated teeth designed for slicing through flesh. These formidable hunters roamed what is now North America during the Late Jurassic (~155-145 million years ago), dominating the floodplains and river environments of the Morrison Formation.

Sourced from the renowned Morrison Formation, this fossil comes from ancient environments that once teemed with iconic dinosaurs like Allosaurus, Stegosaurus, Apatosaurus, and Diplodocus.

Specimen Highlights:

• Dimensions: 6.03 inches at its longest point
• Condition: Well-preserved, solid fragment with repairs but no restoration.
• Provenance: Morrison Formation, Late Jurassic (legally sourced from private land).
• Authenticity Guarantee: 100% genuine dinosaur fossil — personally acquired from a trusted paleontologist who collects in the Morrison Formation.
• Display: Comes with a custom display stand.
• Bonus: Includes a custom fossil description card with Allosaurus facts, geological context, and a human size reference to help visualize the impressive scale of these animals (adults reached 25-35 feet long and weighed 1.5-3 tons!).

This substantial yet compact rib fragment offers a direct connection to the powerful anatomy of Allosaurus — imagine holding a piece of the ribcage that once protected the vital organs of one of the largest and most fearsome predators to ever walk the Earth.

Ideal for paleontology collections, natural history displays, educational use, cabinets of curiosity, or as a standout gift for dinosaur lovers and fossil enthusiasts.
