Of course, all chordates ( animals with backbones, or vertebrates, have skeletal systems, have you not seen elephant skeletons in museums- including mammoths- tusks fossilize, they are bone, but trunks do not! Most mammals have a two-piece tibia and fibular leg-construction with another bone on the side of the lower leg for support. study this on Museum reconstructions. There you have it, tusk tusk, and no bones about it, Soft body parts, such as trunks on elephants decompose and do not fossilize with very rare exceptions of frozen mammoths in Alaska and Siberia.
