La universidad que renuncia a sus espacios culturales abdicta de una de sus tareas centrales: incomodar la inercia, ensanchar la mirada y disputar el sentido común.

fyi it was Wilhelm G. Tilesius, 1802. now you know who did it 😁

I completely agree!

A brainozoan 😁

A supercolony of the freshwater bryozoan Pectinatella magnifica. Each patch on the large mass is itself a colony of animals. The colonies grow on a common base (in that sense, similar to coral) which is gelatinous. Each animal (or 'zooid') has a crown of tentacles used for suspension feeding.

Another cool ammonite 🧪

Meet Iskra’s glitter worm! ✨

The World Register of Marine Species released the annual list of the top-ten marine species for 2025, including this beauty, which was named and described by @scrippsocean.bsky.social grad students Avery Hiley & Kiirah Green, alongside Professor Greg Rouse.

Yep, that's not a cowrie (Cypraeidae), but a Cassis or similar, a helmet shell

Melanella are eulimids, typical parasites of echinoderms

Daily mollusk. A very beautiful pyrite lined ammonite 🧪

Received a review request for a journal I wasn't aware of. Manuscript title and abstract were fanciful.

An opportunity to "discover" 😆 that Springer Nature copied MDPI with a bunch of (semi)predatory journals named "discover something".

Be sure not to review or publish in these journals. ⚒️ 🧪

Daily mollusk. Cool work - but, umm, a specimen not being an original type cannot be considered a paratype. This, my friends, several of you should know 🧪

A chelicera-bearing arthropod reveals the Cambrian origin of chelicerates - Nature Megachelicerax cousteaui gen. et sp. nov. is a large soft-bodied arthropod from the middle Cambrian of Utah featuring massive three-segmented chelicerae, along with five pairs of pseudobiramous prosom...

Wow! Nice reconstruction and video. Those legs look a bit like those of horseshoe crabs 🧪

The lower Miocene Scaphopoda of Chile Scaphopods (Class Scaphopoda, Phylum Mollusca), commonly known as tusk shells, are univalve mollusks exclusively from marine environments that live buried within the substrate. Within this class there...

New paper out about Scaphopoda. Tremendous work of my student Javiera Roco. Open access 🧪

A large gray concretion broken in half and revealing five partial cockle shells that are white to light brown in color. It's sitting on a beach.

#molluskmonday Some spectacular Clinocardium shells in a ~40-50 lb concretion on the beach in Santa Cruz. These are earliest Pliocene (~5 myo) and from the Purisima Formation; each is about 6-8 cm in diameter.

I love nautiloids 🧪

We need more of this

Is that first authors or all authors? Could be interesting to compare them. I expect some of us alpha males have no problem to include women as coauthors, but giving first author place might be different. I hope I'm wrong.
