Reconstruction of the sphenacodontid pelycosaur Dimetrodon grandis from the Early Permian of Oklahoma and Texas (USA). I started this work back in 2018 and even drew a head and torso without a sail, but soon abandoned it. Later, I tried to revive it by changing the position of the tail (initially it was more undularly curved), but I did not go beyond a pencil sketch of the parts untouched by the pen. In January of this year, I finally took up Dimetrodon seriously. In the process, soft tissues were added to the jaws, teeth were corrected, tail, legs and sail were drawn, and wrinkles were added to the skin of the neck and trunk. I'm glad I finally drew this species. The tail is turned a bit too short, but overall the drawing is not bad. :)
Dimetrodon is one of the most famous animals of the Paleozoic era. Its numerous remains were collected in the Red Beds of Texas along with the bones of other Early Permian vertebrates. Other remain were found in other US states, Prince Edward Island (Canada) and Germany. It's known by tall sail formed by vertebral neural spines. With massive head and big canine-like front teeth it was fearsome predator. Many species of Dimetrodon existed, ranging from 90 cm to over than 3 meters in length. As pelycosaur synapsid, it was a distant relative of mammals, including us.
