Belinurus horseshoe crab locked in stone during the Carboniferous, but back in the light of day again now, and on display in the Fundy Geoscience Museum in Parrsboro. #FossilFriday ⚒️

Thinking about turning this into a print somehow. Do you think people might be interested in stuff like this?

This is (in my obviously biased opinion) a great paper that I wish more people would read (not least because it took us several years to hone it down to its final form).

Taxonomy is far from complete but it also is not "complete enough" to warrant the disinvestment seen in ithe field and natural history generally. Museums and herbaria need funds to store, curate, and describe species and taxonomists need to be paid to do it www.nature.com/articles/s44...

What time is it? It’s #Cheliceratime! Finaly found the time to talk about Megachelicerax cousteaui with @penelopeclaisse.bsky.social for today's entry! All the basic infos are here but if you want to learn more, there’s more in the thread below!⬇️🧵 #cambrian #paleoart #arthropod #chelicerate 1/6

Excited to see this restudy of the large Devonian scorpion Praearcturus out today - neatly falsifying some recent supposition that it was not a scorpion at all, and supporting a synonymy between three different species that I've suspected for quite some time! onlinelibrary.wiley.com/doi/10.1111/...

Amazing reconstruction of a famous eurypterid site! Here's one member of that fauna, Acutiramus macrophthalamus (UMMP IP 86635).

420 Million years before the reign of Mamdani, two Acutiramus wake up from their daylight slumber as thousands are Eurypterus begin to invade the shallow, warm waters of New York. This is the Fiddlers Green or Bertie Formation, a Silurian lagerstätte known for its eurypterids🧵

I still find strange things in the woods.

Welcome back to #Fossilfriday Here is a "sea scorpion" or the Eurypterid Eurypterus remipes. This specimen comes from the Upper Silurian Fiddler Green Formation in Herkimer Co, New York. This happen to be the state fossil of New York. Some such as the Pterygotids could reach enormous sizes!

It's finally time to transport over to BlueSky for valentines day my recounting of what I guess passes as a love story from the Viking age; a tale of two poets and their pursuit of one women. Without further ado, I give you a modern telling of the Icelandic saga of Gunnlaug Serpent-tongue. (1/45)

New paper with @peterjwagner3.bsky.social, @wrightam.bsky.social, Jen Bauer, and Maggie Limbeck! www.cambridge.org/core/journal...

TLDR; it is too early to stop doing taxonomic & natural history work and exclusively do meta-analysis; our existing datasets are highly structured & biology is weird. we shouldn't assume we already know enough to extrapolate a species' needs for conservation- we still need taxonomy & autecology

Brendan gives a great summary of our latest paper.
