Today there are a whole bunch of events today,for me it is avian ancestors,fight for funds,the herbivore thing and the boss event,I have avian ancestors as I have not yet unlocked monsters of the deep yet. Which is at level 35. I am not sure where do I invest my coins? I know that only 2 of these events are for coins,but I just spent a lot of coins on mods today for modded battles,so I have very little coins left. My best pterosaurs are 2 Zhejiangopterus at level 10. I know that Avian Ancestors rewards much better because you are guaranteed a super rare,but still,I really want the prehistoric plan eaters pack.
