Green River Insects

  • This project was commissioned by Fossil Butte National Monument for a diorama depicting the fauna from the Green River Formation.  We were commissioned to sculpt about 28 different arthropod models that are exquistedly preserved in the matrix.  This created a unique challenge because some of the details preserved could not be over looked.  This is represented in the skipper butterfly, the patterning is preserved not only on the wings but also in an alternating pattern on the distinct antennae of this creature.  Sizes of these models range from 0.2 inches (Fungus Gnat) to the largest was 5.5 inches (Silk Moth).  The greatest challenge was sculpting the smallest models, which were done under a microscope, to add to this there were multiples, so we had to figure out how to mold and cast these tiny bodies, legs and wings.  This had pushed my expertise to the limits, to achieve this we tested many different rubbers and plastics and some of the models actually used 3-4 different plastics. But in the end, after all the trials and cursing, the results were worth it!
