Dimetrodon Dinosaur XL

Dimetrodon, Tooth Lizard

Dimetrodon, meaning "Two measures of teeth", was a predatory Synapsid
genus that flourished during the permian period, living between 265-280
million years ago. Synapsids are more closely related to mammals than to
true reptiles such as Dinosaurs, lizards and crocodiles. Dimetrodon had
a high, arched, flat structure running along the length of its back, This
feature is presumed to have been used by the animal for regulating body
temperature, such as by absorbing the warmth of sunshine. The most striking
feature of Dimetrodon has been the one meter long protrusions at the back
of the spine, the spinous processes, also referred to as spines. These
spines have wide bases and then form long and slender with pointed tips.
The spines were believed to have been connected by a solid skin, which formed a sail on its back.
