great question. I wasn't sure if I could get away without having a jawset or not. I cut the mouth out of the manikin and hollowed it out a bit. Then I placed the dead squirrel into the mouth and arranged it so that no teeth were showing and checked all around to see if it looked too contrived. I also re sculpted The Yotes liplines using epoxy to rest on the squirrels body. It looked pretty convincing so I took lots of pictures of the form holding the squirrel. I then skinned out the squirrel and repositioned it in the form mouth like the pictures. The head with squirrel was placed into the freezer. The next morning I sawed off the lower jaw and carcass cast the frozen squirrel body( removed the legs) using plaster with hot water and salt. the plaster mold came out OK so I made a form with urethane. i carved and sanded a few details and set the eyes in Apoxie Sculpt. I tanned the squirrel skin in Krowtann and then mounted it before I mounted the Coyote. It fit perfectly just as planned.
