I was under the impression that “therapsid” always referred to a kind of synapsid reptile and was distinct from “pelycosaur” another kind of synapsid think dimetrodon. From Wordnik.com. [Controversies in Evolution: 'Jurassic beaver' unearthed in China - The Panda's Thumb] Reference
Because the fossil evidence of the transition from therapsid to mammal is extensive, detailed and well-studied, it is not surprising that most creationists make no mention of it. From Wordnik.com. [What a difference a day makes. - The Panda's Thumb] Reference
“We arbitrarily group the therapsids as reptiles we have to draw a line somewhere but were they alive, a typical therapsid probably would seem to us an odd cross between a lizard and a dog, a transitional type between the two great groups of backboned animals.”.

As Romer puts it, “We arbitrarily group the therapsids as reptiles we have to draw a line somewhere but were they alive, a typical therapsid probably would seem to us an odd cross between a lizard and a dog, a transitional type between the two great groups of backboned animals.”.

Cross sections of therapsid bones reveal a series of small holes called Haversian canals, which are typical of fast-growing, warm-blooded animals and which are absent in cold-blooded reptiles, indicating that the therapsids developed a progressively more mammalian warm-blooded metabolism as time went on.

The therapsid-mammal transition was completed with the appearence of the morganucodonts in the late Triassic: The axes of the two jaw hinges, dentary-squamosal and articular-quadrate, coincide along a lateral-medial line, and therefore the double jaw articulation of the most advanced cynodonts is still present … The secondary dentary-squamosal jaw hinge had enlarged in the morganucodonts and took a greater proportion if not all of the stresses at the jaw articulation.
