#Vertebrates
I guess now would be a good time for my first post here. Yesterday we published a new paper on the incredible ecosystem of tetrapods and other vertebrates in Science. It has been years of work - but we got there in the end. Thank you to everyone the contributed to this work ❤️
An early Triassic bone bed excavated at 78°N changes the story about how marine life recovered after the most cataclysmic extinction in Earth history ~252 million years ago.

If you are at #SfN2025, don't miss Huihui's poster tomorrow (Sunday) morning at MM6 (PSTR095.13)! He has developed methods for barcoded connectomics across many vertebrates, from frogs to NHPs, and is comparing the single-cell anatomy of the song systems of zebra finches and parrots!

The fact of the matter is that once an invasive population is established it’s almost impossible to remove it completely. The most effective tactic is prevention. Failing that, the second-most effective tactic is probably deploying millions of parasitic wasps (does not work on vertebrates)

Before birds ruled the skies, pterosaurs did. A newly described Australian species — Haliskia peterseni — offers a fresh look at how these ancient reptiles once soared over the Early Cretaceous seas, revealing more about flight, evolution, and life in a vanished world.

I know he’s just a little toady that makes jellyfish look like vertebrates but at this point I’m wondering if Mike Johnson was in the Epstein files somehow
Speaker Johnson is officially keeping the House in recess again next week. This will be the eighth consecutive week the House has been out of session. The chamber hasn't met since Sept. 19. Adelita Grijalva, who was elected on Sept. 23, has not been sworn in.

Gar have the slowest known rate of molecular evolution of all jawed vertebrates, reducing speciation rates. The 2 living genera evolved 105 million years ago. The oldest articulated vertebrate skeleton of the Cenozoic is a gar from shortly after the Chicxulub impact that killed the dinosaurs

A lot of vertebrates keep growing throughout their lives.
Why do humans stop growing at some point?

🦖 Daily Paleo 🦖; Kosmodraco spp.

From Paleocene North America, the up to 5 meter "adorned dragon" belongs to a clade of reptiles called the choristoderes. It had a very blunt snout and a triangular skull much broader behind the eyes. It fed on fish and small vertebrates

Walking upright has a bunch of thermal advantages if you’re a warm-blooded animal and having two free hands is good for using tools and you have 4 limbs because you’re part of the lineage of quadrapedal vertebrates. If we were cephalopods we’d be trying to make 8-10 armed flexible robots instead

Adding to my Middle Earth life list, the Giant Sungazer (Smaug giganteus), endemic to highland grasslands in South Africa. They live in self-dug burrows and eat invertebrates and small vertebrates. Low and slow birthrates leave them vulnerable. #herps #lizards #NaturePhotography 🌿

Are vertebrates the only animals capable of emotional contagion? What about invertebrates? In this new paper from the Feng lab, they show that 🐝s tested in a cognitive bias task were influenced if they were in contact with a conspecific in a positive affective state! www.science.org/doi/10.1126/...
Positive affective contagion in bumble bees
Affective contagion, a core component of empathy, has been widely characterized in social vertebrates but its existence in any invertebrate is unknown. Using a cognitive bias paradigm we demonstrate p...

Perhaps in a furry world where not all vertebrates get anthropomorphized, the furry fandom would still emerge in that universe.

It's just amusing to think about. Imagine a stoat guy dressing up in a deer fursuit, assuming that ungulates didn't become bipedal and sapient in the setting.

Wait excuse me?!?! My entire life the 5 main categories if vertebrates were mammals, birds, reptiles, amphibians, and FISH. What the fuck do you mean fish as a scientific concept isn't real? This is like learning vegetables aren't real all over again.

Ghost bats (Macroderma gigas) are Australia's only bat species that feeds on large vertebrates. On a recent fieldwork trip to AWC's Pungalina-Seven Emu Sanctuary, we visited one of their feeding caves where we found remains of owlet nightjars and rainbow bee-eaters caught by bats 😮. #WildOz

Sheathbills, the most terrestrial of Antarctica's vertebrates, have the chance to fully exploit the many new and empty niches that will appear on the continent. Millennia of speciation lead to new genera such as the crane-like Maudisae and Palithikisae 🐤 #spec-evo #specevo #digitalart #worldbuilding
