Description

A male "fox-faced finback" pelycosaur (early mammal relative) Secodontosaurus does his best to woo a female by presenting her with a fish, bowing, and showing off his neon blue fin.

Interesting how colors indicate clade: the brightly colored male looks way more reptilian, almost amphibian, while the brown female looks mammalian.

Also, Secodontosaurus was named in 1936, a century after Thecodontosaurus (1836). That'th jutht thilly.
