From the Permian Period to the early Triassic Period, mammal-like reptiles came in all shapes and sizes. Some were large and powerful predators such a Gorgonops while others became small yet adaptable survivors like Diictodon. I like Diictodon because it was a soul-crushingly cute little critter that resembled a scaly gopher with tiny tusks. If they remade Caddyshack, I would love to see Bill Murray try to chase a Diictodon across a golf course with C4. Despite being reptiles, Diictodon possessed a number of traits in common with its mammal descendants such as living in burrows and developing an inner ear. Their adaptability is what has allowed Diictodon and its descendants to survive the Permian mass extinction. In my dinosaur series, I am planning to introduce a reverse engineered mammal-like reptile that lives a similar lifestyle to Diictodon. Instead of gophers, I will be drawing inspiration from the naked mole rat or the shrew. Despite being in an ecosystem full of dinosaurs and monsters, I think something as small and cute as Diictodon would be a nice ray of sunshine.
