Atmospheric oxygen levels and temperatures.
Briefly: fossils and their chemical/isotopic signatures and the types/distributions of organisms (and things like fossil charcoal, plant types, oxygen‑sensitive fauna, O isotopes in shells) record past climates and atmospheric composition. Volcanic activity is inferred mainly from volcanic rocks and ash layers, not the fossil record itself.
