Description
This is one of my favorite ancient reptile animals.
The pelycosaurs were a group of no mammalian synapsids.
For its strong appearance with large fangs, and with a large bela on its back (like a spinosaurus)
they are mistakenly confused with a dinosaur (to the point that they even appear in toys in boxes and bags in children's stores)
but it's not dinosaur.
Because they walked with their legs spread out to the side like a lizard instead of directly below them.
Dimetrodon was a synapsid, a member of a group of reptiles that has a single opening (fenestra)
just behind the eye socket in the skull.
The primitive synapsid Dimetrodon is probably the most familiar example of a pelycosaur.
he reason that it is regarded as in any way mammal-like is the presence of teeth that enabled the creature to "chew" its prey and to aid ingestion. Modern-day carnivorous reptiles generally "gulp" their prey whole.
Chewing demands specialised teeth and the jaw muscles to go with them. Chewing is also characteristic of animals that are primarily herbivorous.
Remarkably, this is also true for some true reptiles including many dinosaur species many of which were herbivorous.
The crucial point to note is the relative sizes of the dentary and surangular bones of the lower jaw.
The surangular bone is greatly reduced in the herbivore. So where does that leave us with the jaw (and the diet) of the "mammal-like" synapsids such as Dimetrodon?
Although this animal is considered to have been carnivorous with large, powerful jaws, it also had two types of teeth:
sharp canines and shearing teeth. It is apparent that these creatures also had the ability to "chew" their food and may be more correctly classified as omnivores.
Their jaw architecture would need to accommodate the musculature required to facilitate this.
However, not all pelycosaurs are regarded as carnivorous. It is believed that the Caseidae and the Edaphosauridae were true herbivores.
A typical herbivorous pelycosaur is Edaphosaurus the popular BBC series "Walking with monsters" escribes the carnivorous Dimetrodon attacking the herbivorous Edaphosaurus. This, of course, is speculation. What is more certain is that both Dimetrodon and Edaphosaurus were cold-blooded creatures using their sails to maximize their ability to capture heat from the sun.
They are mainly distinguishable by close examination of their cranial architecture.
Scientist Evolutionists believe it to be a transitional form and that synapsids were the ancestors of modern mammals, but evidence shows Dimetrodon to be fully non mammalian synapsids. The Dimetrodon was cold-blooded like modern-day reptiles and walked on four legs. Its legs sprawled out to the side and it had a large tail that made up a large proportion of its body length. It is thought that it moved much like crocodiles do today.
