Codex Eurypterida: A Revised Taxonomy Based on Concordant Parsimony and Bayesian Phylogenetic Analyses Eurypterids, also known as sea scorpions, were aquatic chelicerate arthropods that were important components of Paleozoic marine and freshwater ecosystems from the Ordovician to the Permian. The group...

It's finally out! 200 years since the description of Eurypterus remipes, the first eurypterid named in the scientific literature, I present a summary of the history of eurypterid research and an updated taxonomy of every known species.🧪⚒️

you guys are being very cynical about this but the real explanation is that bears and Bigfoot are buddies. They like to hang out and do stuff together

OK, this is wild.

In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.

It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

What the HELL?

Probably one of the most exciting recent developments in Mesozoic paleontology is recognizing that at least a few important branches of modern life, such as dinosaurs & ants, likely originated in Gondwana (Southern Hemisphere). Now, let's find Early Cretaceous ant nests! 🧪🐜

Two balck and white photographs showing the dorsal (back) surface of a fossil in a rock. The fossil is darker than the surrounding rock, and has a body starting with a bit of a point, then a front half, like a spider except a bit suqarer, and a posterior that - unlike a spider - is segmented. It was some legs visible, but much of them is buried in the rock. There is a (4mm, if you're intetested) scale bar on the image.

For #FossilFriday, meet Plesiosiro. This is a ~315 million year old weird arachnid, found near Birmingham in the UK. It's a lovely fossil but even so figuring out where it sits on the arachnid tree of life has been... annoyingly challenging. Nowadays, we are fairly confident that it...

Pareidolia fans, rejoice! After a long break I decided to revive my blog and wrote about Eusceptis effusa, a small noctuid moth from Ecuador with a spider-like pattern on its wings. A neat optical illusion! You can read about it here:

A grasshopper is camouflaged on a dried plant against a dark background. The grasshopper’s oval shape, brown coloration, and  mottled texture give it the appearance of a dried leaf, enabling it to blend in with the plant.
