This is really cool! I was thinking of making something around a dinosaur-age civilization for this contest too actually, but I could never have given it such a detailed backstory as you have. I think the map(s) could use some texture to be a bit more interesting, but maybe you were already planning that? Also, maybe it's just me, but that font doesn't look optimally readable… It's cool and fits the sci-fi aspect, but personally I'd use something more basic.
