In part 3 of the series, we are introduced to the Thrinaxodon, a small cynodont found in the early Triassic period. Only slightly larger than the broomistega, this burrowing creature had many early hallmarks of modern day mammals. This, of course, presented some artistic challenges as the thrinaxodon’s design leans closer to that of an bristled, toothy lizard, but I would often use long snouted dogs for reference.
Speculation abounds as to how the real life pairing came to be, but in all honesty, it’s probably not too far off from the depiction above. A little more on just how that works next time.
