Synapsids dont' get mentioned often on the DML. Here's a new paper about some 
of the critters that early archosaurs likely ate....

Cranial morphology of Permian and Triassic Therocephalia of Eastern Europe is 
revised. The Therocephalia are regarded as an order of the subclass 
Eutherapsida of the class Theromorpha. Phylogenetic relationships are 
reconsidered and a tentative taxonomic scheme of the order is proposed. 
Biomorph evolution of East European Therocephalia from the Middle Permian to 
the Middle Triassic are discussed.
