Hyolithes

A side cut of a rock showing small conical shapes within it.

YELL-92021 and USNM_35218: Hyolitha YELL-92021 (pictured) was collected from the Pilgrim Limestone and is housed with the Yellowstone collection. Hyolithes gallatinensis (USNM 35218) was collected from the Snowy Range Formation and is now reposited at the Smithsonian National Museum of Natural History. Hyoliths do not resemble any living organism today, making them very difficult to study. But, they were most likely ocean bottom dwellers and like trilobites became extinct at the end of the Permian.; Megan Norr; March 2016; Catalog #20791d; Original #YELL_92021
