In 1956, D.M.S. Watson observed that sauropsids and synapsids diverged very early in the reptilian evolutionary history, and so he divided Goodrich's Protosauria between the two groups. He also reinterpreted the Sauropsida and Theropsida to exclude birds and mammals respectively, making them paraphyletic, unlike Goodrich's definition.

difference between synapsids and sauropsids Reptilia, on the other hand, traditionally includes the bulk of the species from both the synapsid and sauropsid branches. The difference between the two is merely that while all of the synapsid reptiles are extinct, some of the sauropsid reptiles survive.
Synapsids: retain the left systemic arch Sauropsids: retain the right systemic arch.-Advantage: Loosing an arch = less friction and a reduction of turbulence in the spot where the 2 arches would meet. Amphibians retain both arches*
The difference between sauropsids and synapsids is defined in terms of the openings in their skull. Synapsids have an extra hole, used to reduce skull weight and provide an attachment point for jaw muscles. Sauropsids began with no holes in their skull, then …

Synapsids evolved from basal amniotes and are one of the two major groups of amniotes, the other being the sauropsids, the group that includes reptiles and birds. The distinctive temporal fenestra developed in the ancestral synapsid about 312 million years ago, during the Late Carboniferous period.
6.2 TH levels in heterotherm sauropsids. Among sauropsids, TH levels vary significantly between birds on the one hand and tortoise, lizard, and alligator (forming the ancient zoological group called "reptilia" that is no longer valid on a zoological point of view; see Fig. 14.3) on the other hand. One important difference between these ...

The key differences between the synapsids, anapsids, and diapsids are the structures of the skull and the number of temporal fenestrae behind each eye.

Sauropsida ("lizard faces") is a clade of amniotes, broadly equivalent to the class Reptilia.Sauropsida is the sister taxon to Synapsida, the clade of amniotes which includes mammals as its only modern representatives. Although early synapsids have historically been referred to as "mammal-like reptiles," all synapsids are more closely related to mammals than to any modern reptile.

• Synapsids retain the ancestral condition and excrete urea. – Synapsid kidney is very efficient at producing concentrated urine. • Sauropsids synthesize uric acid. The water used in synthesizing uric acid is recovered when it precipitates.
After just a few million years, basal amniotes diverged into synapsids (primitive relatives of mammals) and sauropsids ().These two groups are distinguished by the number of gaps they have in their skulls — synapsids have one gap behind each eye hole, while sauropsids have two.
