"We are the only natural history museum in Riverside County, which is roughly the size of New Jersey and has more than 2.5 million people...we decided that offsite programming would become a significant part of our outreach efforts."

I suppose that would explain why there haven't been periodic reinvestigation of the site itself! Tricky.

That's news to me! There is so much unanalyzed material in the academy that I hadn't thought much about reopening the site. At least anytime soon.

I should probably hide this paper...
From the person who once extracted the oldest DNA, comes a study that got none out of 6,000-year-old elephants. Or 0.01% to be precise. The worst possible PR for using aDNA to study archaeological ivory. But success stories are coming soon...

For anyone keeping track at home....Port Kennedy Cave has some v large samples of Irvingtonian mammal taxa--crying out for modern re-analyses! Megalonyx wheatleyi, Tapirus, Mammut and a whole raft of large carnivores.

I enjoy citing these papers when I can say they were outright, bonkers, wrong. Otherwise, nah.

Not as pretty as the old Fisk maps, but Roger Saucier's maps in his Geomophology and Geologic History of the Lower Mississippi Valley (1994) have ages assigned based on radiocarbon dating, and I think a better understanding of the processes involved.

Can some museum just do a blacklight survey party in their collections after hours and report everything that glows? Every 6 months there’s another one of these and I’m starting to think maybe it’s not that special/there are some interesting patterns we could pick up with broad sampling.

Oxygen supply through the tracheolar–muscle system does not constrain insect gigantism - Nature New evidence suggests that diffusive oxygen transport through the tracheolar–muscle system is not the limiting factor on insect body size.

#fossilfriday it’s been a very busy week visiting the collections @ucmpberkeley.bsky.social to study the gomphotheres houses here. Enjoy the three holotypes I have had the pleasure of studying/scanning this week: Megabelodon minor, Gomphotherium cingulatum, and Trilophodon simpsoni!

"'There is no 11,000-year-old ash layer underneath the Monte Verde II site," Dillehay told Live Science in an email. "They are studying a different context in the area and are projecting that into the site from elsewhere.'"

Another archeology debate that is secretly geology (stratigraphy)....

The distribution of power and inclusiveness across deep time Democratic practice in the premodern world was not the exclusive domain of Greece and Rome.

Democracy isn't a modern luxury—it's a political strategy with deep roots.

In our new study for Science Advances, we analyse 40 different societies and develop a framework for measuring human governance along a collective-autocratic axis.

Three panel comic. Panel 1: young man in a hoodie looking morose and sitting on a swing set. He says “she’s breaking up with me…” Panel 2: next to him is a glyptodon, an early ancestor of armadillos. With his head in his hands, the young man says “what do I do glyptodon?” Panel 3: the glyptodon says “I’m like an early ancestor of armadillos. The young man angrily replies, “are you even listening man?”
