More acid rain and more aquatic and subterranean animals than birds or dinasores? Calcareous shells would desolve away, but leathery cuticles would not.

Well, if gravity can't hold helium and hydrogen, Cl is excessive and there is to few nitrogenus atoms let's cut the Cl and switch the HE and H for more N and O2.

Better?
