Not technically a dinosaur, the dimetrodon is much more closely related to mammals than reptiles. The dimetrodon spends much of its time sunning on rocks near sources of water. When it grows hungry, it can move with shocking speed for short periods of time. A dimetrodon’s bark is both loud and distinctive, sounding like a truncated cross between an alligator’s roar and a lion’s growl. Dimetrodons are usually about 7 feet long, and can weigh up to 450 pounds.
Although it often remains motionless for long periods of time, a dimetrodon is highly territorial and reacts to intrusions with sudden and terrifying speed.
Burst of Speed (Ex): Up to three times per hour, a dimetrodon can increase its land speed to 60 feet for 1 round as a free action. During this round, it gains a +2 dodge bonus to its Armour Class.
