InGen Carnivore Profile: Dimetrodon

Dimetrodon is mostly seen to be a solitary animal that lives and hunts alone, though occasional group feedings are known to occur when scavenging on carrion. Females with nests become extremely aggressive and will defend their young fiercely from anyone or any animal that ventures too close, including cannibalistic males.

Though it is rarely recorded, Dimetrodon is a capable swimmer and will often enter water to cool itself off during times of intense heat.



On Isla Muerta, Dimetrodon primarily competes for food with the theropods Piatnitzkysaurus and Deinonychus. Up in the valleys, all three predators are seen to coexist. In one on one encounters, Deinonychus will quickly surrender carcasses to a hungry Dimetrodon instead of challenging it, though sometimes it will fight if desperate enough. Piatnitzkysaurus occasionally tries to defend kills against Dimetrodon, though will usually retreat most of the time unless they have young with them. But as of this month, sightings of Piatnitzkysaurus actively fighting Dimetrodon in one on one confrontations have been recorded by observers. One such occurrence involved a lone male aggressively challenging a Dimetrodon that had ventured into it's territory in search of food, resulting in a fight in which both animals were injured, with the theropod suffering nasty bites to it's left leg and right arm while the Dimetrodon was left with a missing eye, bloody wounds on it's side and a chunk of it's sail bitten off, though both had died from their injuries two days later. The pseudosuchian Ornithosuchus can also sometimes be seen confronting Dimetrodon at kills. However, predators such as Ceratosaurus, large Abelisaurs and Postosuchus are avoided at all costs.

On Isla Grande, the main competition of Dimetrodon includes Alectrosaurus, Marshosaurus, Fukuiraptor, Prestosuchus, Sarkastodon, Archaeotherium and Kaprosuchus. Strangely, Dimetrodon is also seen to coexist with the huge lizard Megalania without conflict, with observers unable to figure out why.
