Learn more when you visit this CMNH100 Icon during your next trip to @goCMNH! Find the Hartley Mastodon in Kirtland Hall of #Prehistoric Life. #goCMNHpic.twitter.com/B4rJnr6gDC

Her teeth, pelvis & tusk indicate that she was a female about 30-35 years old. The Hartley Mastodon offers up info to both #paleontologists & #archaeologists; for instance, the mysterious absence of her leg bones provide possible evidence of human hunting.pic.twitter.com/eB5JR0EEWu

TGI#FossilFriday.   @goCMNH's Hartley #Mastodon – named after the excavator who discovered her in Columbiana County, Ohio – is a rare example of the now-extinct American mastodon (Mammut americanum). #Radiocarbon dating tells us that this animal died approx. 12,900 years ago..pic.twitter.com/3kZcNY4tbG

New #tech is changing the way we view specimens – literally! Stop by the #CurrentScience area this Sunday to chat with Hailey Majewski, Digital Asset Developer, as she tackles #3Dscanning casts & specimens from @goCMNH collections. #goCMNHpic.twitter.com/wKng6MR3Bt

75% eyes + 25% fluff   Guess WHOoOoO’s open on Tuesdays now? Beginning June 1, @goCMNH weekly hours will be expanded to Tuesday - Sunday, 10 a.m. to.  5 p.m!

#Tortoise outlaws, Bonnie & Clyde, are in the NEW Thelma & Kent H. Smith Environmental Courtyard today! @goCMNH guests in the area should remain calm & be advised of a low-speed pursuit. The Courtyard is open to guests throughout daytime hours & available for private rentals.pic.twitter.com/VRqx6YTHOF

Catch a few minutes of a partial #LunarEclipse w/ May’s #Supermoon! Key times are tomorrow, May 26 at 4:47 & 5:45 a.m. While #Cleveland won’t get the same #celestial show as California or Hawaii, we can still look for a reddish tinge as the #moon sets in the west. #goCMNHpic.twitter.com/rjr4ZYmDsP

On June 10, @goCMNH welcomes Dr. Suzanne Simard for a discussion of her new book, “Finding the Mother Tree.” Join us for an evening that will profoundly change the way you view #forests & their connections.

Using #radiocarbon dating of preserved maize from two Hopewell culture sites, researchers discovered that the grain only gained agricultural importance several centuries *later.* A nice example of the continual need to test old conclusions w/ new data. https://www.cambridge.org/core/journals/american-antiquity/article/abs/new-dates-and-carbon-isotope-assays-of-purported-middle-woodland-maize-from-the-icehouse-bottom-and-edwin-harness-sites/94E624BB1561B51F197AFF2E27CDF071 …pic.twitter.com/XDnOFxIVrD

Ah-MAIZE-ing. The consumption of #maize (corn) is synonymous with precontact cultures of Eastern North America. But a recent paper co-authored by @goCMNH Dr. Brian Redmond, rearranges the previous belief that #Hopewell people first cultivated the grain ~2,000 years ago...pic.twitter.com/jz9GtbuFvt

Delilah, the #spottedturtle, offered expert paleological assistance as @hypothecait assembled a 50 million-year-old #tortoise shell today! #WorldTurtleDay Stop by our #CurrentScience area every Friday-Sunday to chat w. @goCMNH scientists & learn about their latest research!pic.twitter.com/P1dZWsceA6

Common snapping turtle or earth-bound “Jabba the Hut?" Science is working on it. #WorldTurtleDay   Be on the lookout! In early summer, many #turtle species are currently looking for suitable mates & nesting sites. Here's what to do if you find one trapped on the road...pic.twitter.com/hefA8eae6n

...with the help of Great Lakes Restoration Initiative funds, this unique modified #alvar habitat first received #Lakesidedaisy seed in 2012, with the first flower stalk being observed in 2014. Now, thousands of plants bloom each year & provide blossoms for #pollinators! #goCMNHpic.twitter.com/L9ZnQeh2CC

Happy #InternationalDayForBiologicalDiversity! A @goCMNH (co-held) conservation easement on Huntley-Beatty Quarry acts as an introduction site for the federally threatened Lakeside daisy (Hymenoxys herbacea). The area is also home to over a dozen state-listed species...pic.twitter.com/qRJVVTb9t8

Everyone: So glad 2020 is over 2021: Release the cicadas How many Brood X #cicadas are expected to emerge? And what’s the periodical-17-year-thing? Buzz over to our #CurrentScience area TODAY to chat with Dr. Nicole Gunter, Associate Curator of Invertebrate Zoology...pic.twitter.com/MjVn9rXKHH

In fact, everything researchers know about #Dunk comes from these massive skull plates & jaw bones. This means scientists can only guess at what the lower two-thirds of Dunk looked like! And we’re open to suggestions #goCMNHpic.twitter.com/tg3cbYXpc8

This chompy #grin is the answer to last week’s #FossilFriday Quiz!   #Dunkleosteus is actually the most commonly collected armored fish from #Ohio Shale. This is most likely due to the massiveness of its dermal bones which resisted erosion long enough to become #fossils...pic.twitter.com/kUl7FYDaeX
