Sphenacodon ferocior

A genus of synapsid from late Carboniferous to early Permian North America. This carnivore was about 3 m. long and had large canine teeth at the front of its mouth for prey capture, and shearing teeth at the back for cutting bite sized lumps of flesh.

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. Black gel ink pen, 2024.

Finally shaded Thermian, so here’s my third finished Auzz pokemon.

To reiterate, Thermian is an Ice type pokemon that uses the sun to charge itself, even being able to use certain Fire type moves. It does this with the help of its abilities with Flash Fire granting an immunity to Fire and Warm Blooded boosting its power and speed under sun.

There’s a few custom moves here but I can’t be bothered to go over them right now but feel free to ask.

This... butt nugget... has sat taunting me for a good long while now. Those spires on its back were a major turn-off for getting it finished (it isn’t even) and indeed, I hated doing them.

Anyway... this is a Dimetrodon fake that uses its blood filled ice crystals to absorb sunlight and heat itself up (a fully heated fella in the bottom left there). It needs to be careful though, if it holds that heat for too long the crystals will melt and it’ll have to grow some new ones.

Pure Ice, contrary to what you may be thinking and it gets Flash Fire or a new ability, Warm-Blooded which boosts the power of Fire type moves (it gets a small amount) and doubles speed when the sun is shining. Both these abilities hopefully make for an interesting Ice type, if not a little risky to play.

I just wanna make you all aware that the two species of the Permian synapsid Sphenacodon were named Sphenacodon ferox and Sphenacodon ferocior, which translate to "fierce wedge tooth" and "fiercer wedge tooth" respectively. Palaeontology is amazing.

Weird Backs Month #07 -- Sphenacodon

A close relative of Dimetrodon (who'll be featuring tomorrow), Sphenacodon lived during the Early Permian (~295-270 mya). Two species are known from New Mexico, USA -- and one possible specimen from the United Kingdom -- with the larger reaching up to 3m in length (9′10″).

Its elongated vertebrae formed a long low dorsal crest, the very base of which seems to have supported strong back muscles. These would have helped to stiffen the spine, reducing sideways flexion as Sphenacodon moved.

While sphenacodonts are often depicted in sprawling lizardlike postures, fossil trackways show a much more upright semi-erect gait similar to that of crocodilian “high walking”.
