Pledging to do something and then simply not doing it is an incredibly effective tactic that relies on us being too trusting and too literal of countries and companies www.theguardian.com/environment/...

This #FossilFriday is brought yo you by the Hell Creek gar that I found in 2012. Fun field fact: Were were stuck at camp for so long due to rain that I got to read @theauthorguy.bsky.social 's hilarious book "Lamb" for the first time. I've been hooked ever since. rmdrc.blogspot.com/2025/02/hell...

Missing Southern Illinois today, especially since this is prime fieldwork weather… no bugs and no plants to get in my way.

Question for the fishy folks. These spines seem like they would be relatively diagnostic, but what acanthodian do these belong to? I’ve never seen anything like them.

How do you measure what isn't there? Elska did a fantastic job leading this paper on how we can measure the volume of changing, 3D spaces inside XROMM skeletal animations. And, importantly, how good are those volume measurements? journals.biologists.com/jeb/article/...

This #paleoart shows 3 views of the Devonian brachiopod fossil Paraspirifer bownockeri; one is reconstructed w/ some epifauna and boreholes. These are fun to find; they're an impressive size (for brachiopods). I had an excellent specimen to use as a reference for this painting. #FossilFriday #sciart

Even if their fossil collections were somehow rehoused at other institutions, the potential closure of the Paleontological Research Institute would be an incalculable loss to specimen-based research. It would also eliminate an immensely important educational facility for students and the public. 🧪

Mark Hollis Armitage, 2025. UV Autofluorescence Microscopy of Jaw Ground Sections from Seymouria , Broili, 1904, Reveals Clots in Vascular Canals. How do we know these are blood clots? I understand the clots are in the microvascular canals, but can we say these are clots caused by asphyxiation?

Myodural bridge in amphibians as well as myodural bridge-like structures in fish. The myodural bridge might be a conserved, but widespread, feature in vertebrates.

Very interesting paper on Amji’s salamander. The stapes possesses a stapedial foramen, something thought to be absent in salamanders and frogs. The skeletal anatomy of more herpetofauna can and should be described via micro CT.

Last Thursday, a publication I coauthored was published in The Zoological Journal of the Linnean Society. In the publication, we provided a revised diagnosis and description of the Pennsylvanian embolomere Calligenethlon watsoni. The data can be accessed @ MorphoSource.org via media # 0006677245
