This is Seymouria, a carnivorous, thieving amphibian.
— Allen, describing Seymouria

Seymouria (name meaning "From Seymour") is a genus of tetrapod amphibian that originated during the Early Permian Era in what is now North America and Europe. An amphibian with many characteristics of reptile, it was also an egg thief of its time.

FactsEdit

Era & DiscoveryEdit

Seymouria lived during the Permian period 280-260 million years ago, living alongside creatures like Dimetrodon and Edaphosaurus. These fossils were described by German paleontologist Ferdinand Broili in 1904, and are now stored in Munich.

Physical AttributesEdit

Measuring around 2 feet (90 cm) long, Seymouria resembled a reptile in its outward appearance. Though, surprisingly, it was not. Instead, it was a type of amphibian known as a reptiliomorph. Seymouria's body was tan with brown splotches and its underbelly was white.

These creatures would begin there lives as tadpoles, much like amphibians do. But when they became adults, Seymouria's and other reptiliomorphs' bodies would sprout scales and gain the ability to conserve water, characteristics reminiscent of the reptiles that had descended from them in the Carboniferous.

Male Seymouria had thicker skulls than the females. It is assumed that the thickness of the skull in males was for use in mating rituals. So if two males would see a female they desire, they would begin to head-butt each other until a victor is declared. Seymouria also had a salt gland located in its nostrils that would excrete any excess salt gained by either the food it ate or from their environment.

Behavior & TraitsEdit

Seymouria was a carnivorous, egg thieving amphibian that lurked in the shadows to feed on other creatures eggs. Seymouria lived in semi-arid climates and spent large periods of time away from water, thanks to the adaptations that they would gain upon reaching adulthood which allowed them to conserve water, much like a reptile. But females would return to the rivers and ponds they once spend their childhood in too lay eggs.

Its diet was purely carnivorous. As they went through their various larval stages their prey was worms and insects. When they became adults they still retained their taste for insects, but coherently widened their variety to smaller amphibians and other creatures.

Adult Seymouria also raided the nests of the megafauna at the time, such as Dimetrodon and Edaphosaurus. This was a risky task, however, for they could end up on the menu of the parents of the eggs they wished to consume. Therefore, Seymouria was too small to make a full frontal attack, so they bide their time until the mothers turn their backs.
