Actually Sphenoceramus; Utah's Platyceramus cycloides in the Blue Gat Shale might get nearly this big. @utahpaleo-ufop.bsky.social

For #FossilFriday, meet Inoceramus : the largest bivalve to ever exist. This genus lived in the Cretaceous seas of North America and Europe.

This one is 178 cm long. And look at these rings ! It must an amazing palaeoenvironmental recorder to work with 😍

#PaleoSky 🦑 🧪 ⚒️
A shell of a bivalve mollusc that was found in 1952 in the valley Qilakitsoq on the Nuussuaq peninsula in western Greenland.

The scientific name of these bivalves is Inoceramus steenstrupi. They lived between 83 and 63 million years ago. These are the largest bivalves ever to exist. It is thought that they lived in an oxygen-poor environment and that they layed unattached on the sea floor filtering plankton and detritus from the water.

The shell is 178 cm (70 inch) long. The other half of the bivalve is in the Geological Museum of Copenhagen. ___

On display at the Greenland Institute of Natural Resources. Link to this new Institute filled with many hallway displays at www.natur.gl/ hey now, "moi" for scale and a line-up of 2014 Nuuk Geoscience Workshop geologists waiting for their turn with the mighty mollusk.

The Nuuk display is geotagged instead of the Cretaceous fossil-bearing rock formation on the opposite side of Greenland.

Interesting a lot of recent theory-focused papers I've been reading about fossils don't acknowledge the vast amount of paleobiological literature on the subject(s) they're discussing. I'm happy folks are excited about fossils but also confused why folks seemingly aren't reading papers about fossils

Excited to announce another #groundbreaking paper by @andrejpaleo.bsky.social and colleagues is just out - should be required reading for all those interested in #paleontology #palaeontology #geology

Glad to share our latest article on the statistical structure of geological time scales. doi.org/10.1016/j.ep... time scales are defined by the most extreme epoch defining events, while we've found that the distribution of the boundaries is itself extreme multifractal! 1/4

I think you're right, likely not about competition. Can't say enough about what an awesome paper you folks have written!

You showed they're a great record of cultural #macroevolution @svalver.bsky.social ! Including my own growing up in the early 1980's 😉 . Loved the shout out to "Battlezone" - that was a challenging game. "Defender" or "Asteroid" examples?? 😃

From traits to collaboration networks, cultural systems provide testbeds for evolutionary theory that biology can rarely match in resolution. Arcade games are just the beginning:

With great joy—and a touch of nervousness—I’m thrilled to share that my first academic monograph will be published by @mitpress.bsky.social in May 2026! It examines the organism–environment relationship in biology from an integrated #HPS perspective: mitpress.mit.edu/978026205282... #evosky #philsky
The Organism-Environment Pairing
In this first systematic book-length examination of the organism-environment relationship in the life sciences, Alejandro Fábregas-Tejeda addresses a crucia...

New paper! The 1st publication from our NSF grant investigating local to global biodiversity patterns in marine invertebrates across the O-S boundary is out! Here, we describe a new crinoid from Anticosti Island & use Bayesian tip-dating approaches to quantify uncertainty in its stratigraphic age 🧪

For perspective, last year, 1.2 million unique visitors used our online educational materials...it's really a need of only 1 or 2 dollars per user, and it won't be an annual ask. Just one make or break 6 month period for an almost 100 year old research institution
