Spiders and scorpions belong to a group called chelicerates, which are arthropods with pincers at the front of their head. Fossil evidence reveals how this group evolved

Delighted to provide a News & Views for the new Cambrian chelicerate described by @cambrianlife.bsky.social & @invertebratepal.bsky.social in @nature.com

Congrats! I love sharks so I am very excited.
It's that time of year again.

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.
"Therefore, we caution against considering our present understanding of organismal natural history and taxonomic sampling sufficiently complete to focus research support *sole*ly on meta-analyses" en.wikipedia.org/wiki/Sole_(f...
In reality these assumptions don't hold up and can be incredibly detrimental to conservation efforts and our understanding of ecosystems.
If you want a simple summary, we put much more effort into studying organisms that we eat or are dangerous to us (or we just like or are easier to sample) and have a bad habit of assuming everything else related to them are exactly the same.
Yes, the name is a pun relating to the founder effect, and came about when we pulled a flounder species in our random sampling of publication effort and blew out our data with a huge outlier.
Excited to present the flounder effect - how our biases in sampling and worker effort impact our view of organisms.
A long term collaboration with @fossilsndcoffee.bsky.social, @bigfacecats.bsky.social, Jon Hendricks, and Curtis Congreve!

A screenshot from the Disco Elysium engine, with an elderly cleaning lady saying "The problem these days is no one wants to work harder to earn more, and they all want to live beyond their means. Everyone expects to own a fridge."
Real sentence from a conversation with my 90 year old grandmother.

Can now share thr latest bit of art I've been working on for my sister in law, one of their family cats.
A photograph of a fossil mammal with spiky fur and a long face.
The Mesozoic mammal Sinodelphys, discovered in China and photographed at the Carnegie Museum, for #FossilFriday. Originally described as a marsupial but now thought to be an early placenta mammal, in my considered opinion this is clearly a creachure. 🧪⚒️

Lol no
Just got notification that a video I was interviewed for on Paleozoic lagerstatten is out, also featuring numerous excellent people including Brenda Hunda, Nigel Hughes, and Derek Briggs.

My linocut horseshoe crab is hand printed on 8” x 8” cream coloured Japanese paper speckled with some tiny brown bark inclusions. The crab is viewed from above and its body is printed with a base of grey, with some darker gold-green especially around the edges to give the impression it is a bit domed and then texture, edges, hairs around the edge of the horseshoe shape and the tail are printed in dark brown.
Day 7 #artAdventCalendar my #linocut horseshoe crab (Tachypeus gigas) in grey, blue-bronze and dark brown on 8” x 8” cream-coloured Japanese paper with bark inclusions. 🧪🐡 They get their name from their horseshoe like shape but they are not crabs; they are chelicerates, more closely related to 🧵
Happy #fossilfriday everyone,
Enjoy a feel good story about one of the Museum of the Earth's high school supporters!
Thanks to big giving Tuesday support, PRI is now within ~400,000 of its end of year goal of ~4 million for the mortgage+ops. We can #SavePRI !🧪⚒️🦣🐚

A view of the headshield of Megalograptus, preserved as reddish-brown cuticle on a pale grey rock. The headshield is generally equilateral in shape, with a rounded front bearing small spiny projections. A pair of round eyes are also located at the front of the head. The surface of the headshield is curved in dense, pustule-like scales.
A fossil of the second appendage of Megalograptus, preserved as dark cuticle on a light grey rock. The appendage is short with robust spines coming off of it.
A view of the body segments of Megalograptus, preserved as dark cuticle on pale grey rock. Four body segments are present, again preserving small, pustule-like scales.
One of the earliest large predatory eurypterids, Megalograptus, for #FossilFriday. Megalograptus is known from abundant - and very unusual - material from the Ordovician of #Ohio, affording an important insight into the morphology of this rather bizarre species. ⚒️🧪
Top songs from Spotify wrapped, featuring Suspirium for the 5th year in a row. 1. Short Change Hero (The Heavy), 2. Suspirium (Thom Yorke), 3. Precinct 4q Major Crime Unit (Sea Power), 4. Francis Forever (Mitski), 5. Enemy (Imagine Dragons, JID)
Top albums from my Spotify wrapped, all soundtracks - 1. Scavengers Reign, 2. Disco Elysium, 3. Hollow Knight, 4. Battletech, 5. Baldur's Gate 3
A view from my Spotify wrapped showing that my listening age is 30.
Fun to see what I've been listening to over the course of what has been, in all honesty, an absolutely terrible year.
Today I’m joining the #GivingTuesday challenge to save the Museum of the Earth. As a Board of Trustee emeritus member, I see first-hand the Museum's impact on educating our community and the world about climate change, biodiversity, and our home planet. Please donate at priweb.org/support.
Now, that could prove useful 🧪
A great overview on benefits, pitfalls, and limitations.
