We’re back with another Chats from Collections! 🦚

This time, we’re taking you behind the scenes of our bird collections move. Our incredible collections team has already moved more than 40,000 specimens, with more still to go!

Our new collections wing offers improved climate control, flat storage for specimens and large, rolling drawers that make organizing and accessing the collection easier.

What an inspiring evening at the Museum!

Thank you to everyone who joined us last week for Conversations with Women in STEAM featuring renowned physicist, Gabriela González!

We’re so grateful to Gabriela for sharing her incredible work in gravitational-wave detection, her journey in astrophysics, and her passion for encouraging more women to pursue careers in STEAM. A special thank-you to our moderator, Museum astronomer Monica Marshall, and to all of our guests for being part of such an engaging and insightful conversation.

We loved bringing our community together to celebrate the discoveries, stories, and people shaping the future of science! 🪐🔭

The Cleveland Guardians have some amazing fans...but we might have their BIGGEST. 🦕⚾️ Good luck tonight, Guards!

🦈 Happy National Fossil Day!
Meet Cladoselache (clad-oh-sell-ack-ee), a shark-like fish that lived in northeastern Ohio during the Devonian Period (~360 million years ago), when it was a tropical ocean south of the equator.

These fossils are found in rocks all over northeastern Ohio called the Cleveland Shale. Cartilage doesn't usually preserve well, but the cartilaginous fish fossils we find in the Cleveland Shale are so well preserved that you can see exactly what they looked like. Sometimes, even their last meal (small fish and invertebrates) is preserved in their bellies!

Want to see these incredible fossils for yourself? You can find Cladoselache and other animals from its ancient ocean home in our galleries.

What did the world look like when some of the earliest stone tools were being made?

A recently released study co-authored by Dr. Emma Finestone, Museum Curator of Human Origins, takes us back millions of years to Nyayanga, Kenya, where ancient human relatives made some of the oldest known stone tools. By studying the sediments and the fossilized plant and animal remains preserved at the site researchers were able to piece together a picture of the landscape these early toolmakers called home.

Want to dig deeper? Read the full paper, along with two of the Museum’s press releases on related research from Nyayanga. Find them all through the link in our bio.
