A private list I made for my interest in cycles, hope it will help

4,404 Bil BC – The oldest dated zircon crystals of Hadean rocks enclosed in sandstone with evidence of liquid water in Western Australia were found,

26°C.
548–238 Mil BC - Climate – The accepted hypothesis seem to be that during the Cambrian period Western Antarctica was beginning to form in the
Northern Hemisphere because of the deposited of large amounts sandstone, limestone and shale’s. Eastern Antarctica was at the equator, where sea
floor invertebrates and trilobites flourished in the tropical seas. There is however some evidence suggesting Antarctic marine glaciations during the
Cretaceous period. This most likely was caused by the uplift along the Transantarctic Rift but was insignificantly minor due to the landmass
position.
