The painted turtle is the most anoxia tolerant tetrapod known to man. Able to withstand lactic acid concentrations of up to 180mM, mineralized tissue breaks down calcium and magnesium carbonate complexes to buffer lactic acidosis. The mechanics of the plastron and it’s contibution to buffering are well studied, but the buffering capacity and mechanics of the carapace are relatively unexplored. The function of this device is to accurately and precisely impart point impact force to a painted turtle carapace to determine mechanical trends in carapace mechancs over the course of anoxia.
