MAGNETITE! Well, probably. They are magnetic, and too tiny to see any other features . . .

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

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.

I did not know juliid snails had a coelacanth-like history. Do you happen to know the publication history that sorted that out? Does anyone know what their hinge is like?

Since we have only known each other a finite amount of time, this is high praise! For this, I think I owe you some fossil fish papers . . .

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

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

Guess who? Printed at about 1/2 scale.

Okay. So Lingula would probably win against any rudist, as long as it managed to kick itself in the right direction with its pedicle.

Thomas Hegna @thomashegna.bsky.social · Jun 3

So the remote control will be able to control it. Without the wheels, the remote is useless.
It's a little toddler RC car. This brach will not win any races. Just like every other brachiopod that ever was.

SUNY Fredonia alum Jasper Glow helped with the assembly. Ishaan Rangnekar and Fiona Rigby helped with the digital cutting.

Thomas Hegna @thomashegna.bsky.social · May 23

Purchased the model on sketchfab from the Cleveland Museum. Cut it into 90 printer-sized pieces. Voilà.

So, Tom, how have you been procrastinating the arthropod cuticle preservation paper? Oh, you know . . .
