I haven't posted anything for a while, so here's some new #paleoart for #FossilFriday: Cetiosaurus in a Middle Jurassic landscape. I've had to compose and execute this in just two days, so hopefully it looks OK! (All data for the plant recons comes from @palaeojules.bsky.social.) #dinosaur #sciart
A long-necked dinosaur walks along a shallow river surrounded by various Jurassic trees, ferns and shrubs. A small predatory dinosaur watches from the nearest riverbank.

Marietta has had an on-again, off-again vertebrate paleo program. I understand they found this skull years back, the only known Apatosaurus skull still attached to the neck, now on display at the Cincinnati Museum Center. We still have this replica, though. Anyways, part of the annual pilgrimage!

On Anarchism.
"The easiest way to explain anarchism is to say that 
it is a political movement that aims to bring about a 
genuinely free society - one where humans only enter 
those kinds of relations with one another that would not 
have to be enforced by the constant threat of violence. 
History has shown that vast inequalities of wealth, 
institutions like slavery, debt peonage or wage labour,
can only exist if backed up by armies, prisons, & police. 

Anarchists wish to see human relations that would not 
have to be backed up by armies, prisons and police. 
Anarchism envisions a society based on equality and 
solidarity, which could exist solely on the free consent 
of participants."

A group of green, slender-limbed Hadrosaurus with iguana-like heads and arched postured amble alongside a shoreline.A pair of noodly-necked, erect-backed Parasaurolophus with skin sails stretching from their crest to their shoulders stand in a forest. Their sails are decorated with large, round markings.A Maiasaura nesting ground cloaked in dense fog. A mixed-age group of hadrosaurs with red and cream countershading mill about in the barren landscape, variably wandering or tending to bowl-shaped nests dug into the muddy ground.Two thick-necked Edmontosaurus with large, tubular nostrils and beaky overbites drink from a river. Their necks, covered in large, subrectangular scales, are decorated with a low ridge of triangular scaly projections. They regard the viewer with a inscrutable, bird-like expressions. Behind them, numerous mayflies dance through the steamy air.

When "Dolores" the Corythosaurus (first excavated by famous fossil hunter Levi Sternberg) debuted in its Hall of Earth History in 1957, the Academy of Natural Sciences quickly became known among locals as "the dinosaur museum." The Academy is much more, but Dolores remains standing. #FossilFriday

Paleodictyon formations have been popping up throughout the last 530 million years, but researchers don’t know what they are. A new study points to crustaceans. www.sciencenews.org/article/paleont…

What's behind 'one of paleontology's most enduring enigmas'?
New research suggests that Paleodictyon — honeycomb-shaped formations perhaps sketched by da Vinci — are not made by soft-bodied creatures.

This is seismic news for fisheries scientists. Northern cod is *the* iconic symbol of total fisheries collapse due to overfishing (and other factors) *and* the iconic symbol of a complete failure to recover for decades afterwards. This is like announcing the complete recovery of bison on land.

If your worldview is shaped by evolution, you recognize most of what we are was inherited and is shared with other living things. Other living things reason, have relationships, love, create, and communicate. This is why basic biology research is really important. It teaches us who we are.

I love that the seemingly endless and bitter academic argument over whether insect wings evolved from the sides of the insect body, or from extensions from near the tops of the legs, has been resolved by finding that the sides of the insect body are just extension of the legs and both are correct.
