Major events from the second decade of the twentieth century in Michigan paleontology include a 1923 paper by O. P. Hay who reported the presence of two identifiable species and one indeterminate form of mammoth whose fossils had been found in Michigan. [14] Interesting whale fossils were also discovered and described from Michigan around this ...

This list of the Paleozoic life of Michigan contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Michigan and are between 538.8 and 252.17 million years of age.
A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral, Hexagonaria percarinata. [1] Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges and depositing them in the northwestern (and some in the northeastern) portion of Michigan's lower peninsula.
Corals were the most common animals found in Devonian Michigan. There were three types of coral found in Devonian Michigan: branching, colony, and solitary corals. These corals are found as fossils in almost every fossil site in Michigan. This is because the Devonian was a time of great reefs, which covered most of the world's oceans.
A survey of Lake Michigan located at least 40 large craters on the lakebed. Initial studies highlighted the spots as unknown shapes, but additional research revealed the craters are filled with ...
