Why does it look real? Because it is real stone! Ossatorum Aeterna is a company specializing in the creation of ultra-realistic replicas of dinosaur skeletons and other extinct or endangered animals. Using an innovative mineral-coating technique, our creations achieve an authentic, museum-quality appearance. This unique approach was born from a simple observation: painted replicas often lack realism, while traditional molds, although more faithful, provide limited detail and restrict the creation of fine anatomical features. Our hybrid technique combines the best of both worlds, accurately capturing anatomical complexity while giving a lifelike mineral texture of natural fossils. The result is arguably among the most realistic replicas currently available for discerning collectors and enthusiasts. Item for Sale Replica Forelimb of Allosaurus (Allosaurus fragilis) – Theropoda Overall Dimensions (with base): • Length: 60 cm • Height: 37 cm • Depth: 15 cm Discover a museum-quality, ultra-realistic life-size (1:1) replica of an Allosaurus forelimb, including the humerus, radius, ulna, and articulated hand with claws. This striking anatomical piece is designed for collectors, museums, and enthusiasts seeking both visual impact and scientific authenticity. About Allosaurus Allosaurus was one of the dominant apex predators of the Late Jurassic, living approximately 155–145 million years ago, primarily in what is now western North America. Reaching lengths of up to 9 meters, it was a powerful, agile theropod that preyed on large herbivorous dinosaurs such as Stegosaurus and juvenile sauropods. Although shorter than its massive jaws, the forelimbs of Allosaurus were strong, functional, and heavily muscled. Each arm bore three large, recurved claws, well adapted for grasping, restraining, and slashing prey during close combat. Unlike the reduced arms of later theropods, the Allosaurus forelimb retained significant mobility and strength, playing an active role in its predatory strategy. This replica highlights the robust proportions and lethal efficiency of one of the Jurassic’s most formidable hunters. Key Features (Superior Craftsmanship) Weight and Stability With the base included, the arm weighs approximately 700g. Its solid construction ensures a stable, secure, and durable display. Mineralized Hyper-Realistic Finish This piece has undergone a multi-step artisanal process, including a hand-applied mineral coating that faithfully reproduces fossilized bone, natural erosion, and subtle sedimentary textures. Carefully directed lighting enhances tonal variations within the mineral layers and brings depth to joints and claw sheaths—creating a convincingly fossilized presence. Exceptional Detail Bone surfaces, articulation points, and claw morphology are reproduced with high fidelity, capturing the rugged anatomy and biomechanical function of the Allosaurus forelimb. Museum-Grade Mounting The arm is mounted on a professional support fixed to a solid wooden base. This museum-style presentation allows the limb to appear dynamically suspended, emphasizing its proportions and predatory design. Material Polymer core coated with Ossatorum Aeterna’s proprietary hand-applied mineral coating, crafted from carefully selected natural rocks, finely ground to achieve an authentic fossil texture and coloration. Scientific Accuracy Based on current paleontological data and reproduced at true 1:1 scale, respecting known proportions of Allosaurus fragilis forelimb anatomy.
