Therapsida [a] is a clade comprising a major group of eupelycosaurian synapsids that includes mammals and their ancestors and close relatives. Many of the traits today seen as unique to mammals had their origin within early therapsids, including limbs that were oriented more underneath the body, resulting in a more "standing" quadrupedal posture, as opposed to the lower sprawling posture of ...
Therapsids were synapsids that began to appear in the Early Permian. They had larger temporal fenestrae (openings of the sides of the skull) than the ancestral pelycosaurs . The most advanced therapsids are the cynodonts, which include mammals .
This list of therapsids is an attempt to create a comprehensive listing of all genera that have ever been included in the Therapsida excluding mammals and purely ...

Skull of E. mirabilis. Estemmenosuchus could reach a body length of more than 3 m (10 ft). [2] Its skull was long and massive, up to 65 cm (26 in) in length, [2] and possessed several sets of large horns, somewhat similar to the antlers of a moose, growing upward and outward from the sides and top of the head.
They were devastated by the end-Permian Extinction that wiped out most other therapsids ca. 252 Mya. They rebounded during the Triassic but died out towards the end of that period. They were the most successful and diverse of the non-mammalian therapsids, with over 80-90 genera known, varying from rat-sized burrowers to elephant-sized browsers.
Moschops (Greek for "calf face") is an extinct genus of therapsids that lived in the Guadalupian epoch, around 265–260 million years ago. They were heavily built plant eaters, and they may have lived partly in water, as hippopotamuses do. They had short, thick heads and might have competed by head-butting each other.
Mees' lines can look similar to injury to the nail, which should not be confused with true Mees' lines. [1]Mees' lines appear after an episode of poisoning with arsenic, [2] thallium or other heavy metals or selenium, [3] opioid MT-45, and can also appear if the subject is suffering from kidney failure.
