As with any project on such a scale (I think it's quite a big project) there are always mistakes.The most glaring one of mine was to a whole creature without realizing I had another one planned. I like to have a variety of different creatures (herbivores, carnivores, air/sea/land adapted) and I had Meganeura planned from the beginning. Maybe it's my affection for the old kid's TV series, but I only realized after I did Moschops that he wasn't needed. I'll put him at the bottom...he doesn't really fit with the rest.
