Titanophoneus

Welcome to the permian about 298.9-251.902 million years ago. at that time, the world is dominated by synapsids like the infamous dimetrodon or the more fearsome inostrancevia

(shi's reconstruction of a CHONKY dimetrodon grandis) this is dimetrodon, the most infamous synapsid of the permian period. unlike his non-finned pelycosaur relatives, dimetrodon has a sail to stabilize his spine & control his body temprerature in a form of thermoregulation

Dimetrodon mainly eats early reptiles, fish and amphibians rather than having plant eaters for a feast. he's a species of dimetrodon grandis, one of the many 20 dimetrodon species. weighting up to 330 pounds and is about 9.8 feet but is underestimated by dimetrodon angelensis, the largest species of thd dimetrodon genus.

(artist's impression of various dimetrodon species for scale)

The first dimetrodon genus was first discovered in the 1870s in southwest USA by american paleontologist: Edward Drinker Cope.

The smallest species of dimetrodon was teutonis almost the 60 cm long and weighted only 14 kg...

The male dimetrodon grandis is resting in the night sky. maybe the seymouria dosen't mind to sleep near him

(shi's art of a seymouria resting with a sleeping dimetrodon)

Sey

Seymouria are a species of amphibian but are more adapted to land more than water

The individuals of this species are robust-looking animals with a large head,stocky limbs,and broad feet and are fairly small creatures and this one is with a dimetrodon for a good-night friendly sleep...

The next morning. seymouria realise that dimetrodons are carnivores so she has no choice but to walk away from grave danger while dimetrodon grandis woke up later.

He dosen't seem aggressive and his sail is wounded.

Dimetrodon grandis walks up in the early morning sky and what he saw were a migrating herd of edaphosaurus...

(shi's art of edaphosaurus pogonias)

Edaphosaurus are one of the first herbivorous vertabrates of all time. they are distantly related to dimetrodon. however the sail of these herbivores look a bit different in shape & morphology. they are more than 3.5 meters in length and probably weighted 300 kg in keeping it's tiny head. like most herbivores, edaphosaurus have a capacious gut and symbiotic bacteria to aid in the breakdown of cellulose and other indestible plant materials.

Dimetrodon then came to check it out then runs to follow the tracks of the herd.

The edaphosauruses seemed frightened trying to scare the predator away with their flashing sails. but dimetrodon can see and locks onto the nearest edaphosaurus. his teeth are sharp and serrated. the recurved rear teeth are for shearing through tough flesh his name means: two measured teeth in reference to his sets of small and large teeth.

The edaphosaurus stands no chance...

And the other members of the herd runs away as fast as they could to escape this fearsome pelycosaurid predator.

But the smell of blood attracts other individuals of his kind...

(another rival... art by:shi)

The other dimetrodon grandis individuals decided to feast on the edaphosaurus. the dimetrodon with the wounded sail (the one we who's the protagonist throughout episode 6) defensed it's kill when another rival entered the scene. but realised he knows better than to defened it for himself...

A few days later. dimetrodon grandis found scavanged food when he founded a cotylorhynchus

(shi's deptiction of cotylorhynchus romeri)

Cotylorhynchus is a herbivorous caseidae synapsid. usually feeding on low-nutrient plants

It's 6 meters long and probably weighted over 500 kg. the cotylorhynchus is curious about dimetrodon grandis, but it's best to leave the predator alone...

Dimetrodon grandis then drags the scavanged meat to eat it later...

(life restoration of helicoprion davisii)

In the northern parts of usa, theres helicoprion

His teeth that are like blades are actually tooth whorls. the unusual saw-like teeth whorld and lack of wear on teeth of helicoprion implies a diet of solf bodied prey as hard shelled prey would slip out of their mouths. the suction feeding is unlikely to have been affected and helicoprion is thought to have been a bite feeder. but whats on the land above are dinocephalians.

In whats now isheevo of russia a titanophoneus is chasing an ulemosaurus.

These belong to the suborder dinocephalia. but this is more than a evolutionary competition between predator and prey even before the dinosaurs. all species of the permian are at an evolutionary arms race on the supercontinent

Pangea.

until the largest extinction event ever occured on earth...

This episode only takes place in the early permian which explains why gorgonopsids and dicynodonts didn't appear in the episode

Titanophoneus protens is a carnivorous dinocephalian from the middle permian in what is bow russia,268-265 mya.it is classified within the family anteosauridae

The teeth are large with 12 large platate incisors followed by 2 canines and various smaller back teeth.the lower platate is the same as the upper but without the canine teeth.the apearance of titanophoneus is reminiscent to the sphenacodontid,pelycosaur,with inclubed dimetrodon

Remains of titanophoneus have been found at isheevo in russia,along with ulemosaurus

The name titanophoneus means titan murderer
