“¿A qué animales pertenecieron estas garras?” – Espectacular Exposición Comparativa de Garras de Dinosaurios Terópodos del Cretácico (Réplicas Museum-Quality de Alta Fidelidad)

Detailed Description (Ideal for a museum website, educational platform, or high-end fossil/replica shop):

This striking museum-style display presents one of the most visually impressive and scientifically valuable comparisons in modern paleontology: a complete size-graduated series of theropod hand claws ranging from small coelurosaurs to the gigantic apex predators of the Late Cretaceous.

All specimens are ultra-high-resolution, museum-grade resin casts produced from original fossils or 3D-scanned holotype material, finished with scientifically accurate coloration and texturing. Every crack, blood groove, keratin sheath margin, and surface detail has been meticulously reproduced under the supervision of professional paleontologists.

Featured species (from largest to smallest):

1. Tyrannosaurus rex – Massive 28 cm (along curve) killing claw from the manual digit I. Cast from one of the finest known specimens (possibly “Sue” or “Stan” material). Deep chocolate-brown coloration with authentic wear facets.
2. Albertosaurus sarcophagus – Large adult claw showing pronounced flexor tubercle and sharp curvature typical of tyrannosaurids.
3. Daspletosaurus torosus – Robust claw with heavy blood groove.
4. Gorgosaurus libratus – Slightly more gracile than Daspletosaurus but still powerfully built.
5. Deinonychus antirrhopus – Famous sickle-shaped claw of the second pedal digit (“terrible claw”). Cast from the Yale specimens described by John Ostrom.
6. Velociraptor mongoliensis – Iconic enlarged pedal claw from the Fighting Dinosaurs specimen, showing the extremely high curvature and razor-sharp tip.
7. Troodon formosus – Delicate, almost bird-like claw with fine striations.
8. Ornithomimus velox – Small, slender claw from a lightly built ornithomimid.
9. Chirostenotes pergracilis – Elegantly curved oviraptorosaur claw.
10. Struthiomimus altus – Very straight and reduced claw typical of advanced ornithomimids.
11. Archaeopteryx lithographica (bonus piece) – Tiny, perfectly preserved manual claw of the “first bird” for ultimate size comparison.

Educational & Display Highlights:

• All claws displayed on custom acrylic risers with bilingual (Spanish/English) identification labels.
• Central sign reads: “¿A qué animales pertenecieron estas garras? Resuelve a lo largo de la muestra exponencial” – inviting visitors to discover the dramatic evolutionary size range.
• Scale progression clearly demonstrates the enormous disparity between the largest carnivorous dinosaurs and their smaller, often bird-like relatives.
• Perfect centerpiece for natural history museums, university departments, dinosaur exhibitions, or serious private collections.

Technical Specifications:

• Material: High-density polyurethane resin with real fossil surface texture
• Finish: Multi-layer airbrushed museum-quality paint and sealing
• Accuracy: Sub-millimeter precision from CT and photogrammetric scans
• Includes full scientific documentation and references for each specimen

This exhibition set is not only a powerful visual statement about theropod diversity and the evolutionary transition toward birds, but also an exceptional teaching tool used by numerous institutions worldwide. Whether for permanent display, traveling exhibitions, or as the crown jewel of a private paleontology collection, this comparative series never fails to generate awe and discussion.
