Another new paper out now: led by Amy Betz from the @bruceslieberman.bsky.social lab on how a variety functional traits did or didn't impact extinction risk in the Plio-Pleistocene-Recent western Atlantic regional mass extinction Of the 16 traits considered, none was correlated with increased risk

Happy to share paper in #Palaeontology led by my former @ku-eeb.bsky.social grad student Amy Betz w/ @jonhendricks.bsky.social @fossilsndcoffee.bsky.social and Portell & Strotz on factors impacting #extinctions in #marine #mollusks. #paleontology onlinelibrary.wiley.com/doi/epdf/10....

Wow—thanks @bruceslieberman.bsky.social for posting the entire issue of Paleobiology vol 51/4 2025 “Punctuated Equilibria at 50”—open access papers from the GSA 2022 50th anniversary symposium! A great community celebration!!

Really excited to have the new issue of Paleobiology @paleosoc.bsky.social out celebrating the 50th anniversary of #punctuatedequilibria #macroevolution #paleobiology #palaeontology #paleontology @nilese.bsky.social www.cambridge.org/core/journal...

Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

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 🧪 ⚒️ #Geology #Paleobio

Temporal stratigraphical boundary densities of different time scales.

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: "The Cultural Macroevolution of Arcade Video Games: Innovation, Collaboration, and Collapse" 👉 doi.org/10.1017/ehs....
