The strange world of mammal evolution is present in these two pieces.  The dog-like cynodont therapsid Cynognathus and the utterly handsome dinocephalian (more like a side branch in evolutionary terms) Estemmenosuchus. Both have been published in Anusuya Chinsamy’s  “Forerunners Of Mammals” previously mentioned in another post. Although probably not as “attractive” as dinosaur evolution… the incipient mammal evolutionary stages are just as fascinating.
