Good books on Therapsids

[CityRaptor]

Since I'm gonna go working on a project regarding these animals ( mainly their inner ears), are there any good books about them?

I know that "Forerunners of Mammals" is about them, but are there more, you would recommend? Especially those with skull references would be useful.

Here is one "On the functional morphology of the gorgonopsid skull" by Tom Kemp (http://users.ox.ac.uk/~tskemp/pdfs/prs1969.pdf) and another "The ear in mammal-like reptiles and early mammals" by Kenneth A. Kermack and Frances Mussett (http://www.app.pan.pl/article/item/app28-147.html)

You can't go wrong with John McLoughlin's "Synapsida". I haven't found many good books on therapsids either, but McLoughlin is a great overview of their evolution

Okay, ordered a copy a few hours ago.

Thanks you all!
