1. A nearly complete postcranial skeleton of the Permo-Carboniferous reptile Dimetrodon is described and figured. The structure and possible function of the spines are discussed, and a mechanical explanation for their origin is suggested. The specimen shows Dimetrodon to have been a long-tailed form. The skeleton is restored and a life-restoration given. 2. Models of the probable musculature of the limbs of Dimetrodon are presented. 

The dorsal axial musculature of certain primitive permian tetrapods

The development of the dorsal axial musculature is traced from Eryops, through Diadectes, to Dimetrodon. lguana, a modern form, is used for comparison. The axial muscles of a primitive form, such as

Anatomy and relationships of Haptodus garnettensis, a Pennsylvanian synapsid from Kansas

ABSTRACT New, well-preserved specimens of the Upper Pennsylvanian synapsid Haptodus garnettensis from Garnett, Kansas, represent more mature individuals than those available previously and indicate

Natural environment and thermal behaviour of Dimetrodon limbatus.

Evolution of bone microanatomy of the tetrapod tibia and its use in palaeobiological inference

Lifestyle is inferred to have been terrestrial for the stem‐tetrapod Discosauriscus, the basal synapsid Dimetrodon, the dicynodont therapsid Dicynodon, an unindentified gorgonopsian, and the parareptile Pareiasaurus, which is modelled as being aquatic, but was more likely amphibious.

Thermal Regulation in Sail Lizards

The sail of Dimetrodon grandis was the end form of an evolutionary series of pelycosaurs that had tended to develop increasingly large sails, with features strongly suggesting an early attempt at temperature regulation.

A New Sphenacodontid Pelycosaur (Synapsida) from the Wichita Group, Lower Permian of North-Central Texas

Two specimens collected recently from the middle Wichita Group of Baylor and Archer Counties, Texas, represent a new sphenacodontid pelycosaur, Ctenorhachis jacksoni, which is distinguished from all other sphenicodontids by neural spines that are only modestly heightened and uniformly blade-like antero-posteriorly.

New Postcranial Material of the Early Caseid Casea broilii Williston, 1910 (Synapsida: Caseidae) with a Review of the Evolution of the Sacrum in Paleozoic Non-Mammalian Synapsids

It is argued that this repeated acquisition of a three-vertebra sacrum in early synapsids was related to more efficient terrestrial locomotion than to increased weight bearing, suggesting that it was not an adaptation to heavy weight bearing.

UV Autofluorescence Microscopy of Oklahoma Permian Synapsid Femur (Dimetrodon Cope, 1878) Reveals Blood Clots in Vascular Canals

It is concluded that the iron in the canals is the crystallized remains of blood that clotted during an asphyxiation event that killed the animal and should be examined under UV fluorescence.

Nocturnality in synapsids predates the origin of mammals by over 100 million years

Recognizing the complexity of diel activity patterns in non-mammalian synapsids is an important step towards a more nuanced picture of the evolutionary history of behaviour in the synapsid clade.
