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

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

I dream of being a long snouted predator in the backwaters of Laurentian rivers, but for now I crush shells with my round teeth and am sad #garweek #scheenstiaposting #totalgroupginglymodi

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.

I wonder if my fish dreams transfer over to her, and make her hungry

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

This #fossilfriday , I wanted to post a very classic Pittsburgh fossil. This is Fedexia striegeli. It’s known from only one specimen (shown here) that was collected during a geology field trip to a roadcut near Pittsburgh in 2004. I credit it as the specimen that made me interested in local verts!

Listen man, I really hate acanthodians. Long time followers (from the X days) know this. But I hate them.
Anyways here’s a pectoral spine of one from the Pittsburgh Coal member of the Monongahela Group. Late Pennsylvanian.

The density of invertebrates in vernal pools is insane. Hundreds of thousands of little crustaceans (fairy shrimp and copepods) that are only alive for a few weeks. Insane that these habitats are not legally protected.

A beautiful day to stand up for science, and to see old friends.

More signs of spring. An eager Ambystoma maculatum migrating last night before the snow. So chunky.

February was a difficult month (and March is shaping up to be the same). But I’m not sick anymore, and working from home on account of spring break. The lengthy winter in the US provided well-needed rest for forests, and signs of spring are starting to pop up. This Epigaea repens is one such sign.
