Three more days until Six Extinctions opens at the Bruce Museum! Check out this amazing life reconstruction of Tiktaalik, the Devonian “fishapod” that Sean Murtha created as a special addition to the exhibition.

Six Extinctions opens at the Bruce Museum in 5 days. We will display a few of our own extinct birds, which perished in the ongoing extinction event caused by humans. These include our beautiful Passenger Pigeons. The last captive bird, Martham died in the Cincinnati Zoo 1914.

Imagine if you stepped on a carpet and it started wriggling away? Arthropleura was an 8 foot long millipede with a weird flattened shape that roamed Permian swamps over 250 million years ago. Encounter this delightful beast and many more at Six Extinctions, opening at the Bruce Museum in 9 days!

Happy to report that our 35x life size Dinoponera ant Buckley has been adopted by the Greenwich Audubon Center! We will miss her, but now that Ants: Tiny Creatures, Big Lives has closed it is great to know she will still be educating people about the miraculous world of natures tiny architects.

Only 10 days until T. rex comes to the Bruce Museum! We are the first North American host of Gondwana Studios' traveling exhibition Six Extinctions, opening June 6. The dinos will be joined by giant millipedes, armored fish, saber-toothed tigers and more! Photo: Richard Harmey

Sunday is the last day of our exhibition Ants: Tiny Creatures, Big Lives. I’ll miss these little guys. One last weekend to see (and smell) the world of natures miniature architects.

We've learned so much about penguins in the past few years! Read about warm-weather cousins of emperor penguins, 60 million year old "proto-penguins" and 300lb giants. My piece in American Scientist is live, with great art by @simone-giovanni.bsky.social www.americanscientist.org/article/dive...

Diversity from Isolation

Fossils of early penguin species reveal the myriad paths these birds took from the sky to the sea, and from temperate New Zealand to the frozen Antarctic.

My life is greatly improved by finding out that you can turn off the horrible system in Word that forces you to activate every comment and go on the scavenger hunt when "Another comment is in progress". Preferences / General /uncheck Enable modern comments.

Happy Penguin Awareness Day! Here's a throwback to our 2023 exhibition Penguins, Past and Present. We are celebrating at the Bruce Museum today with a special 10 question Penguin Round at tonight's Bruce Museum Trivia. Meet us at 6pm for pizza, drinks, and prizes!

For #MineralMonday, take a peek at our lovely canvasite. This is one of my favorite pieces in our Tiny Treasures case. The blue coloring comes from vanadium, but what makes this mineral so special to me is have the clusters look soft like fluffy little cotton balls!

Happy Thanksgiving! I'm thankful for Centuriavis lioae, a 10 million year old fossil relative of turkeys. It was a lot of fun describing this stunning specimen with Catherine Early, Kate Dzikiewicz, and Amy Balanoff. The fossil is named after our amazing museum colleague Suzanne Lio.

Ants: Tiny Creatures, Big Lives is officially open at the Bruce Museum! Enter the tunnel and you will meet "Buckley", our five foot long scaled-up Dinoponera ant. Buckley is named after her creator, the great Dan Buckley. The smaller ant is my daughter, dressed as an alate queen for the opener.
