This is why the kneecap is a useful thing

So uh

They found a whole lot of the rest of Spicomellus, aka one of the oldest ankylosaurians

Turns out it's also the spikiest

And apparently sacral shields and tail weapons go all the way back too

It’s Fossil Friday, so let’s get a leg up on the weekend with these colossal limbs! Snapped circa 1899, this archival photo from the Museum’s digital collections depicts a Museum preparator standing beside the fossilized limbs of dinosaurs discovered in Wyoming. The larger bones belong to sauropods while the smaller bones belong to a theropod—likely Allosaurus.   Want to learn more about dinosaurs? Plan your next visit to the Museum!

Happy Fossil Friday! This archival image, snapped sometime before 1960, depicts duck-billed dinosaurs on display, side by side, at the Museum. Also known as hadrosaurids, these massive herbivores were the dominant plant-eaters in many areas of the world during the Late Cretaceous about 85 million years ago. In addition to their duck-like beaks and webbed front feet, hadrosaurs had powerful jaws with hundreds of blunt teeth that were ideal for grinding fibrous land plants.

See these hadrosaurs and more at the Museum! Plan your visit.

Bones of the Arm and Hand

evangelical christians are missing out with the whole not believing in evolution thing, that shit's cool as fuck

like look at this shit

this is an example of what are known as homologous structures. because of the similarities in bone structure, it suggests that all creatures shown here have a common ancient ancestor

essentially these all have the same bones, but shifted, stretched, fused, and warped by evolution and time to serve the purpose the animal needed

and they all do have a common ancestor, as does all life on earth

look at this crazy ass tree showing EVERYTHING started as a teeny tiny ancient bacteria and evolved and grew over millions of years to fucking EVERYTHING, all life being connected to this singular point

idk abt you guys but to me that's cool as fuck and I hate that people don't teach it in schools based on what a book said

[quark-nova-deactivated20260116]

i hate how mammal-centered and human-centered the last diagram is but otherwise yeah that's absolutely amazing

How do horses flick their tails?

they got bones in there

[tales-of-misc-fandoms]

Okay I. I know this is about the tail which like that’s cool and all and fun facts BUT-

ARE YOU KIDDING ME?? THEY LITERALLY CALL THE THIRD LONG BONE OF THE HIND LEG THE METATARSAL?! EXCUSE ME BUT THAT IS NOT A FOOT-

Just like. Why. Why would you call it a metatarsal. W. H. Y.

[bunjywunjy]

sorry man, it's called that because that's exactly what it is.

the foot. Bone

My uni used to host this bio-art photography thing to show the pretty side of science and I had this pic waiting for over a year now, but they didn’t make an another edition, so I might as well post it here!

These little dudes are 5-day-old zebrafish larvae, fixed with paraformaldehyde and stained with Alcian blue to visualize cartilage. And the background is just the dark field of the microscope and some random mess floating around in glycerol.

This is what #bonecancer looks like

[neo-jurassica]

These #extinct animals are Discosauriscus Pulcherrimus, that lived approximately 275 million years ago in the late Permian period. The carbonised #bones were found near Boskovice, in the Czech Republic. 🇨🇿

Bird man

Pierre Belon (1517–1564) was a French traveler, naturalist, writer and diplomat. Like many others of the Renaissance period, he studied and wrote on a range of topics including ichthyology, ornithology, botany, comparative anatomy, architecture and Egyptology.

In his L'Histoire de la nature des oyseaux (1555) he included two figures of the skeletons of humans and birds marking the homologous bones. This is widely used as one of the earliest ideas on comparative anatomy.

Enjoy, have fun, cheer up

"In a floor of a triclinium one of the panels is that of a skeleton, with a text “Euphrosynos”: “enjoy, have fun, cheer up”. A notice explains that in the 1st century BC skeletons started to be used. This mosaic is from the 3rd or 4th century when scenes of bathing and banquets (convivium) represent the most important activities of Roman socio-cultural life."

"SOX9 keeps growth plates and articular cartilage healthy by inhibiting chondrocyte dedifferentiation/osteoblastic redifferentiation"

Ablation of the chondrogenic transcription factor Sox9 leads to rapid cessation of longitudinal growth and articular joint destruction.
