    I think people get confused because afaik the reason today’s bugs may be smaller due to the lower oxygen levels.

    Doesn’t really apply to T-Rex tho.

      Which has to do with how bugs breath through their exoskeletons which is a function of surface area. Lots of O2 can support larger surfaces area bugs.
