Dimetrodon pair, artwork
Dimetrodon pair, artwork. Dimetrodon (meaning two-measure tooth ) lived in the early Permian period, around 270 million years ago. It was not a dinosaur, but a pelycosaur (class Synapsida), a primitive ancestor of the mammals. It was a predator that grew to a length of 3.5 metres and weighed about 250 kilograms. It had a large dorsal sail that was believed to be used to regulate its body temperature. Although cold-blooded, Dimetrodon showed early mammalian traits, such as enlarged openings at the back of the skull (fenestra), sharp canine teeth and shearing teeth. It is thought that Dimetrodons and other pelycosaurs gave rise to the therapsids, which were the direct ancestors of the mammals

EDITORS COMMENTS
This artwork showcases a pair of Dimetrodons, fascinating creatures that roamed the Earth approximately 270 million years ago during the early Permian period. Although not classified as dinosaurs, these pelycosaurs were primitive ancestors of mammals, belonging to the class Synapsida. The Dimetrodon was a formidable predator, measuring around 3.5 meters in length and weighing about 250 kilograms. One striking feature of this ancient creature is its large dorsal sail, which scientists believe served as a means to regulate body temperature. Despite being cold-blooded, Dimetrodon displayed early mammalian traits such as enlarged skull openings at the back (fenestra), sharp canine teeth, and shearing teeth. These remarkable characteristics suggest that Dimetrodons and other pelycosaurs played an essential role in the evolutionary transition from reptiles to mammals. They are believed to have given rise to therapsids – direct ancestors of modern-day mammals. Through this stunning illustration, we catch a glimpse into prehistoric times when life on Earth was vastly different from what we know today. It serves as a reminder of our planet's rich biological history and highlights the importance of understanding our evolutionary roots through paleontology and biology research. This print from Science Photo Library captures both the scientific significance and artistic beauty found within nature's intricate tapestry – showcasing an extraordinary species that once bridged an evolutionary gap between reptiles and mammals.
