Kentucky The Petoskey stone and its cousin, the Charlevoix stone, are found along Lake Michigans western shore from the northern tip of the lower peninsula to as far south as Manistee. The rugose coral, which fed on small organisms by capturing them with tentacles, has been extinct for 250 million years. Besides Dunkleosteus, fossils of a few other ancient armored fish have been uncovered in Michigan: Titanichthys, which was as big as Dunkleosteus, but didnt have as big of a bite; the foot-long bottom-feeder Bothriolepis; and the tiny Ptyctodus, fossils of which have been found only in Russia, Arizona and Michigan. When the glaciers dug into the deep layers of sediment where the fossils rested, the remains were released and transported to the lake basins. The state of Michigan used to be covered by a warm, shallow sea and was later an unforgiving glacial landscape. [13], Major events from the second decade of the twentieth century in Michigan paleontology include a 1923 paper by O. P.

Smithsonian National Museum of Natural History. University of Waterloo Earth Sciences Museum. By taking into account what the rock is that they came from, what kind of animals there are, what kind of animals theyre relatedto and other pieces of information, we can determine the environment from which they came and learn a little bit more about the history of the location, said Jenifer Bauer, research museum collection manager at the University of Michigan Museum of Paleontology. Along the shores of Michigans lower peninsula, one can be rewarded in finding Michigans official state stone, the Petoskey stone. It grew as large as 20 ft. long and weighed up to a ton - about the size of a great white shark - and is characterized as a hypercarnivorous apex predator, able to use its beaklike mouth to chomp through other armored fish, arthropods and mollusks.
