Thanks for the large critters vs. gravity ping.

I would like to see more investigation of the differences in oxygen and mitochondria (and thus ATP and muscle strength) before and after the big impact about 65 million years ago.

I have read that insects are limited in size because of their inefficient respiratory systems — but there were dragonflies six times larger than present dragonflies.
