Dimetrodons are prehistoric sail-backed reptiles with splayed, lizard-like hips, rather than true dinosaurs. The average version is 1d5+5 feet long, weighing 10d24+60 pounds. Giant versions are 1d10+10 feet long and weigh 8d50+300 pounds. Although they are hard to kill, they will consume victims even while being attacked, giving some opportunity for additional attacks or escape.
