Since some people on the DML also work on non-dino tetrapods, this new
paper may be of interest:

A taxonomic revision of Batropetes (Amphibia, Microsauria) from the
Rotliegend (basal Permian) of Germany.

The genus Batropetes is one of the most completely preserved
representatives of the microsaur family Brachystelechidae. Previously,
the only species to be described was Batropetes fritschi, based on 19
mostly poorly preserved specimens from the Döhlen Basin in eastern
Germany, and one referred specimen from the Saar-Nahe Basin in western
Germany. Reexamination of this material demonstrates that the referred
specimen differs from the type material, and it is named Batropetes
niederkirchensis n. sp. in this study. The two species differ in the
shape of the prefrontal and postorbital, the width of the interorbital
region, the number of presacral vertebrae , the degree of ossification
of the scapulocoracoid, and the position of the obturator foramen. The
functional interpretation of the skull and the locomotion apparatus
suggests that the genus was terrestrial, living near the lakes, where
they are preserved in the sediments.
