And even though it’s “technically NOT a dinosaur….”
i never said it had to be all dinosaurs. I am open to any prehistoric animal used in either a realistic, scientifically accurate way to pure imaginative fantasy. So your synapsids fit in there perfectly well.
This thread is for Dinosaurs, Pre-Dinosaurs like the Synapsids, Prehistoric Reptiles ( plesiosaurs, pterosaurs etc ), prehistoric mammals, prehistoric insects, pretty much anything extinct used in either a realistic or fantasy way.
