Why Bronze? The Foundry Connection
The decision to cast in bronze grew out of an unusual academic-program pairing at Mesalands Community College. The school operates one of the largest community-college bronze foundries in the country, with students learning lost-wax casting techniques used for fine-art and architectural bronze sculpture. When the museum was conceived in the late 1990s, the natural-sciences faculty proposed using the foundry to cast dinosaur skeletons for display — a technically demanding project that produced extraordinarily durable, finely detailed mounts.
Lost-wax bronze casting involves making a wax replica of each individual bone, encasing it in a refractory ceramic mold, melting the wax out, pouring molten bronze in, and then chasing and polishing the result. Each dinosaur skeleton thus represents hundreds of individual castings, joined into a complete articulated mount. The process takes years per specimen and represents both significant student labor and significant material cost — bronze is not cheap — but the resulting casts will last essentially forever and capture surface texture (bone foramina, growth lines, tooth serrations) at a level of detail unavailable in plaster.
The museum's collection now includes a 40-foot Torvosaurus, an Allosaurus, a Camarasaurus, a Stegosaurus, a Pteranodon, a Mosasaurus, multiple smaller theropods and ornithopods, and a growing collection of Triassic creatures from the region's Chinle Formation. Some mounts are full skeletons; others are partial. The Pteranodon, mounted to a wall with wings spread, is one of the most photographed exhibits. Read the labels — they identify which specimens are cast from originals found nearby, which are cast from holotype specimens at other major museums, and which represent reconstructions based on multiple individuals.
