Periods of Earth's history were Precambrian (4.5 billion - 542 million BCE), Cambrian (542 million - 488 million BCE), Ordovician (488 million - 443 million BCE), Silurian (443 million - 416 million BCE), Devonian (416-359 million BCE), Carboniferous (359-299 million BCE), Permian (299-251 million BCE), Triassic (251-200 million BCE), Jurassic (200-145 million BCE), Cretaceous (145-65.5 million BCE), Paleocene (65-56 million BCE), Eocene (56-34 million BCE), Oligocene (34-23 million BCE), Miocene (23-5.3 million BCE), Pliocene (5.3 to 2.5 million BCE), Pleistocene (2.5 million - 10,000 BCE), and the Holocene (10,000 BCE - present).
The extinction events in the Ordovician may have been caused by Tritovores and the Sycorax.
No Silurians exist in the Silurian era.
Some Saturnyn came to the Devonian period through a crack in time and plan to build a home there.
Macra may have been present in the Carboniferous.
The era of Silurian civilisation was likely in the Cretaceous.
Krynoids may have fallen to Earth in the Paleocene and taken over the planet if not for the intervention of time travellers.
The Fendahl influenced Earth in the Miocene.
Light came to Earth in the Pliocene, and may have encountered the adventurers at this time.
