New paper out with Sarah Losso and Javier Ortega Hernandez : "These legs were made for walking: 150 years of trilobite appendage morphology and evolution" authors.elsevier.com/c/1nN4m2weR2... #trilobite #paleontology #arthropod #palaeontology #fossils

Happy #WorldHorseshoeCrabDay!
 These spinning #horseshoecrab (Limulus polyphemus) embryos are developing inside their eggs, just weeks away from hatching. Despite their name, horseshoe crabs are closer relatives of spiders and scorpions than crustaceans.

We've collaborated with the Patterson Library in Westfield to make some summer reading kits for local libraries to fit with this year's theme of "Unearth a Story." www.fredonia.edu/news/article...

School's out at SUNY Fredonia, but we're still doing stuff. www.fredonia.edu/news/article...

Fossils of Western New York: The Fossils in Our Backyard

YouTube video by Thomas Hegna

Come and see me talk about the geological history of western New York, Thursday, June 4th at 6:00pm, at the Patterson Library in Westfield, NY.

Some students spend spring break on the beach. Ours explore the desert. www.instagram.com/p/DYSR3DbAHJ...

A great article was published in the Chautauqua Gazette last week detailing the environmentally-related research that our students are doing. Read the article here (pages 1 and 6): www.chqgazette.com/PDF/CG4-20-2...

Over spring break, I took a group of 17 students to Utah for an extended field trip. We spent most of our time in the House Range near Delta, UT, looking at Paleozoic rocks.

Do you ever wonder about trilobite appendages? Literally everything ever known has now been reviewed by Sarah Losso @thomashegna.bsky.social @invertebratepal.bsky.social 🧪⚒️🦑 osf.io/preprints/pa...

For paleo folks, there is a kickstarter project out there to support a massive photorealistic extinct mammal book. If we can increase the support for the book, it will expand to 600 or even 800 pages! www.kickstarter.com/projects/152...

Tomorrow!

Little known fact about the glacial sediment near Lake Erie in our area. Sometimes, you can see a swath of this sediment in the swash zone of the beach—the waves sort them differently because they are denser than the other sediment. #sunyfredonia #geology #lakeerie #sedimentology #glacialsediment

Our Dunk is nearing completion. It now has a stand! #paleontology #geology #Devonian #sunyfredonia #3dprinting

The water level of lake Erie is at a point where we can reach parts of Point Gratiot that I have never been able to visit. So, I took some students on an impromptu field trip this afternoon to see the Kellwasser event exposed at the Lake Erie Beach. #sunyfredonia #geology #paleontology #devonian

More pictures from measuring stratigraphy with Dr. Hegna's class out at the Sheridan Bay Park. Included is some meta-photography with SUNY Fredonia's Roger Coda (marketing and communications). #geology #stratigraphy #fredonia #lakeerie #sunyfredonia

Another 3d printed skull to guess. It is harder than it looks.

Guess who!

A beautiful day to measure the Hanover Shale. Found a crinoid-filled lens amongst the layers. #Fredonia #geology #stratigraphy

Another way we spent our summer vacation: www.fredonia.edu/news/article... #fredonia #geology

I don't think I am exaggerating when I say this is the fastest brachiopod ever. Introducing the Brachio-Bot. #fredonia #paleontology #3dprinting

The Trilo-bot is now fully operational!

Guess who? Printed at about 1/2 scale.

I bring you the latest advance in lophotrochozoan technology: The Brachio-bot®

New paper out describing the first fossil ovaries and unfertilized eggs in a primitive horseshoe crab. #paleontology #xiphosura #ordovician

So, Tom, how have you been procrastinating the arthropod cuticle preservation paper? Oh, you know . . . #Devonian #dunkleosteus #3dprinting
