OH MY GOSH THEY'RE REAL IT'S REAL ULTRA RARES BESIDES MELANISTICS/ALBINOS EXIST!! Megalosaurus is otherwise "this is a dino in Paleo Pines" for me– nothing wrong with 'em, I just get distracted by the species that excite me more– but not only is it NOT ALB/MEL, it's blue in keeping with my ranch color theme! YOINK
Oh actually I should mention Byrginsunn (Protecting Sun) who I got the literal game-day before: Sunray-colored euoplocephalus are Ultra Rare, but you automatically meet this one during story stuff and can befriend it. The only problem for a long time was that attempting that would softlock your game because it was bugged. But they fixed it, so I said "fine I'll take my free UR" and it gets to sit in the Illegal Warm-Color Dinos corner.
Doesn't count though!! Megalo FIRST.
