This list of the Paleozoic life of Iowa contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Iowa and are between 538.8 and 252.17 million years of age.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
This is a list of mammals of Iowa. The list includes species native to the U.S. state of Iowa and introduced into the state. It also includes mammals currently extirpated in the state.

The paleozoic fossil record of Iowa spans from the Cambrian to Mississippian. [1] During the early Paleozoic Iowa was covered by a shallow sea that would later be home to creatures like brachiopods, bryozoans, cephalopods, corals, fishes, and trilobites. Later in the Paleozoic, this sea left the state, but a new one covered Iowa during the ...
Rare in the fossil record are the homobasidiomycetes (a taxon roughly equivalent to the mushroom-producing species of the agaricomycetes). Two amber-preserved specimens provide evidence that the earliest known mushroom-forming fungi (the extinct species Archaeomarasmius legletti) appeared during the mid-Cretaceous, 90 Ma. [31] [32]
The mushroom is commonly called "Thiers' lepidella". [ 4 ] Then in 2016 Scott Redhead and his associates created the genus Saproamanita for the saprophytic members of Amanita ( sensu largo ) but the new name Saproamanita thiersii is very controversial and not broadly accepted.
Much of its remaining habitat is located on the Driftless Area National Wildlife Refuge in Iowa. Known from fossil evidence about 400,000 years old, it is one of many glacial relict species that remain in the Driftless Area, a glacier-eroded plateau that now makes up parts of Iowa, Illinois, Minnesota, and Wisconsin. Much of the area was ...
