Wooly mammoth skull

This was my winter holiday project that I made for Tampere Vapriikki museum exhibition Ice Age Giants. The plan was to make natural size wooly mammoth skull with tusks. Some of the skeletons that have been deep in acidic bogs have this kind of nice deep brown color.

Inner structure is made of steel tubing. It was tricky to invent very light, but strong structure that could hold force caused by long tusks.
All bones are made of insulation foam, polyurethane foam and plastic padding. Surfaces have 2 layers of epoxy resin colored with pigment powders. I used 1,5l resin and 6 pieces of insulation foam sheets. Rough shapes were cut with Japanese saw. Other shaping was done with different sanders and hot wire cutter.
This project produced huge amounts of static plastic dust, that could be found everywhere next weeks.

Skulls weight is altogether 15kg.
