Sue (dinosaur)
Sue is the nickname given to FMNH PR 2081, which is the largest, most extensive and best preserved "Tyrannosaurus rex" specimen ever found, at over 90% recovered by bulk. It was discovered in August 1990, by Sue Hendrickson, an explorer and fossil collector, and was named after her. After ownership disputes were settled, the fossil was auctioned in October 1997, for US $8.3 million, the highest amount ever paid for a dinosaur fossil, and is now a permanent feature at the Field Museum of Natural History in Chicago, Illinois.
Michigan fossil hunting
The oldest living fossils found in Michigan have been found in the Negaunee iron formation near Palmer, MI at the Empire Mine. The fossils are of a primitive, filament-like ancestor of algae. Scientists have determined the fossils to be 2.1 billion years old. http://www.michigan.gov/documents/deq/Oldest_Fossil_304663_7.pdf They are found in thin layers in one section of the mine. The fossil is known as Grypania cf. spiralis which is preserved as a corkscrew-shaped, or spaghetti like marks that look like random O's, C's and 6's.Many of Michigan’s fossil sites are located on lake shores. An example is Point Betsie, near the small town of Frankfort, Michigan. Erosion from wave action sometimes damages the fossils but fossils such as corals or bryzoans can be found here.
