Physical appearance and biologyEdit
Edaphosaurus was a large mammal-like reptile which resembled its distant relative Dimetrodon. It had a large and long sail running down its spine which was vividly coloured and patterned. However, unlike Dimetrodon, it had a small head with chisel-shaped teeth designed to grind up plant matter: Edaphosaurus was one of the first truly herbivorous reptiles.
Edaphosaurus was blue with yellow stripes. Its sail had an eye-shaped pattern on it.
Behavior and traitsEdit
In Walking with Monsters, Edaphosaurus was shown living in herds from tens to hundreds of individuals. In these large groups, they nurtured and protected their offspring.
The sail of Edaphosaurus was a sophisticated temperature-controlling device. The sail worked as a solar panel. In the morning, the creature was turn its sail towards the sun to absorb the heat. Doing this allowed it to warm up. During midday, Edaphosaurus probably turned its sail away from the sun to cool itself down.
Its sail could also be used as a method of intimidation and display. It could flush blood into the sail to create a bright pattern of color, similar to what a Stegosaurus did when it flushed blood into its plates to scare away predators. This was useful for many situations, i.e. being attacked by a Dimetrodon, but not always, as the predators of the early Permian evolved into being intelligent enough to recognize the bluff. Still, adult Edaphosaurus was practically invulnerable due to their size, and even Dimetrodon preferred to hunt juveniles instead.
Edaphosaurus' sail appears near the very end of the opening titles.
It was spring spring, and the Edaphosaurus herd were resting underneath the conifers to shield their sails from the sun. The next day, as the adults rested, the youngsters played and tested their strength.
However, over a hill, a female Dimetrodon watched them. As the carnivore edged towards the herd, they noticed and scattered. As the Dimetrodon locked onto a juvenile Edaphosaurus, it attacked and killed the youngster. It then fed on the carrion until a group of larger male Dimetrodon successfully challenged her for the kill.
Behind the scenesEdit
Edaphosaurus appeared in Primeval in Connor Temple's database. The image used was from Walking with Monsters.
A study conducted in 2011 has cast doubt on the theory of Edaphosaurus' sail's use as a tool for thermoregulation. Suggesting that it's only purpose was simply to attract mates.
Contrary to what Walking with Monsters states, Edaphosarus is not the world's first herbivorous reptile. This title goes to Eocasea martini, a caseasaur discovered in 2014.
Petrolacosaurus is not the ancestor of synapsids like Edaphosaurus. Ironically, they lived together in the same time period and the same area.
The skin texture of Edaphosaurus and Dimetrodon are slightly off. They had scutes on their skin, similar but different to the ones on crocodilians. They are believed to lack the scales of lepidosaurian reptiles. Its' also thought they could have had fur.
