This specimen of sphalerite, pyrite, and quartz comes from the famous Huarón Mine in Peru. Operations at this mine began in 1912 and continue to this day by the Pan American Silver Mining Company. #minerals #crystals #pyrite #sphalerite #museum #museumcollection #behindthescenes

Crinoids are the less well known relatives of sea stars and sea urchins that belong to the phylum Echinodermata. This particular fossil (WM/P 596) was found in the Devonian Period rocks of Milwaukee by Kenneth Gass. #fossils #paleozoic #museum

As we continue our look into the new collections, here is a 1.5 billion year old smoky quartz cluster from Wausau, Wisconsin. This specimen is 7x5cm with 3cm tall crystals. #museum #minerals #crystals #wisconsin

The WESM is busy organizing our collections. Enjoy our weekly posts highlighting specimens we are working with today. This is WM/M 825, an impressive example of calcite crystals on dolomite from Joplin, Missouri. The largest crystal is 18 cm tall! #crystals #geology #museum

Though the weather outside is frightful, the museum and shop remain open our normal hours for December. Stay warm!

UW-Madison isn't the only campus in Wisconsin that has a geology museum — those in the Appleton area may want to check out the @WeisMuseum on the @UWOFox campus in Menasha. uwosh.edu/weis/

Happy #FossilFriday! This is the skull of a woolly rhinoceros (Coelodonta antiquitatis) which roamed Eurasia during the Pleistocene Epoch. Standing over 6 feet tall at the shoulders, this creature was about the same size as a modern white rhino but completely covered in long fur!

Starting today, the WESM will be requiring masks for all employees and guests. Thank you for your cooperation.

Summer has arrived! Starting next week the museum and gift shop will be open for our new regular hours: Wed-Fri 12 to 4:30 and Sat 10 to 4:30. We will be closed Sun-Tues and holidays.

More dinosaur research from UWO! Using metal replica dinosaur teeth and cow bones, Dr. Peterson and colleagues were able to determine that young T. rex could bite with bone crushing force. uwosh.edu/today/97385/cr…

Today we recognize those who gave their lives in the service. To all the sacrifices military women, men, and families have made, we at the WESM thank you.

Happy #InternationalMuseumDay! Come see the world-class Wisconsin minerals from the Barlow Collection this Saturday from 10-5pm. This amazing specimen comes from the Montreal Iron Mine in northern Wisconsin. #geology #mineral #crystal #wisconsin #museum
