A bit of a pleasant surprise to wake up to actual snow this morning. Hopefully it stays this way this winter!

New paper in JSP: Gonçalves & Luccisano reassess the taxonomy and phylogeny of Aeduellidae, Carboniferous ray-finned fish from Decazeville Basin, France 🐟
Results hint at a North American origin… or convergent traits that muddy the family waters.

Yet another reason why data centers are terrible.
1/4 I typically do not use preprint services, but our findings are important to the residents of Bessemer, Alabama impacted by the Marvel Project...a mega datacenter that will have a huge environmental impact.

Vestiges of a once great radiation persist in another “ganoid” of North American slackwaters (Amia, the bowfin). Halecomorphs, of which Amia is a part, include things as unique as the marine pelagic predator Caturus, from the Jurassic of Germany. #fossilfriday #neoptposting

Brief trip home before going across the pond next week. Fall colors are popping in the hills and the sounds of trains echoing through the fall air of the Allegheny valley reminds me of the model train setup at the Kamin Science Center that I loved as a kid.

Here's another one you won't have seen: a waiting-to-be-prepared specimen from the Green River Fm. Probably Cuneatus. Maybe they'll be ready for #GarWeek next year!

Oh that's the posterior clavicle element (clvb in the figure below). I had to check Grande & Bemis 1998 for confirmation.😀

Holosteans are weird. Try to guess what this cursed bone is. From a modern fish, if that helps

Way to go Emily!!
I love working at a museum because that means I get to create fantabulous SciComm activities 🐟🐡 Visitors will have the chance to match 3D printed living and extinct fish jaws to what they think the fish eats, based on jaw and tooth shape.

BEHOLD the GARgantuan Alligator Gar!!!
This is the largest Alligator Gar I’ve encountered; at over 7 feet 10 inches (240 cm) and approximately 55 inches in girth, its weight is estimated at 300 pounds (136 kg)!
A true river monster, among the largest caught, tagged and safely released! #GarWeek
