Rux the Pumice Eater Dragon.

Rux is about the size of a chimpanzee to us but with the wing shape and wingspan of a condor. His kind hail from the desert lands of barren plateaus, volcanoes, and lakes and rivers of lava. Rux was hatched and raised in a dormant volcano and although he can hunt and tear meat from bone with his sharper front teeth but he had incredibly thick dental batteries for molars for chewing and crushing up the mineral rich rocks found around volcanoes. When it comes to proteins and vegetables Rux grows his own plants with volcanic ash as fertilizer and he prefers not to actively hunt but instead scrounges for carrion.
