i was at the museum and I saw this cast of a dinosaur who had this. Interesting kind of second rib cage type deal? Unfortunately I didn’t get a photo of the placard but i think it said it was related to the tyrannosaurs
looks like this. also if you know what that lower rib plate is its so cool to me and I’d love to know it’s name and purpose
That's a pretty cool skeletal mount, looks like a tyrannosaurid of some sort, I would guess Daspletosaurus?
To answer your question, those are called the gastralia, also known as the "belly ribs"! They seem to be present in all theropod dinosaurs but were lost in birds, and they also show up in prosauropods as well as non-dinosaurs like crocodiles, tuataras and plesiosaurs. Basically they form a more protective surface over the vulnerable underbelly.
The shape of the gastralia can actually give us a good idea of what the overall shape of an animal's belly was, in the same way that ribs define the shape of the sides! For example, some plesiosaurs have very flat gastralia which likely means they has a flatter belly, but others are more rounded.
The re-mounting of SUE the Tyrannosaurus involved closer study of their gastralia, and the way that the bones fitted together showed that SUE and other Tyrannosaurus had a much rounder "pot belly" that previously assumed!
So yeah gastralia are cool and they give us a neat insight into the shapes of prehistoric animals!

“Anatomy of a Hug" by artist - Luna Lu
Elves are highly adaptable to their local terrain, hence the differing characteristics of Wood Elves and Sea Elves. In more recent times this adaptability has given rise to newer Elf types such as Mall Elves, Cubicle Elves, Hardware Store Lighting Section Elves, Skate Park Elves, and Highway Elves.
Anatomical Works Sculpted in Crystal and Glass
Santa Fe-based sculptor and jewelry designer Debra Baxter combines glass, bronze, crystal, wood, and found objects to create ghostly sculptures of human forms.
For many of her recent works Baxter shares with Roq Larue Gallery that she drew inspiration from the phenomenon of the “Ghost Heart.” In this medical procedure, a heart is cleansed of all of its blood cells and then injected with hundreds of millions of new blood steam cells which cause the heart to begin beating again. Baxter is interested in how this concept explores the complexity of existence, walking the line between life and death.

i made my first infographic on a topic ive been very interested in lately: wings! ive seen a lot of anatomical sins relating to wings lately (i am not exempt from this) particuarly involving pterosaurs so i put this together to help artists who may be struggling with drawing wings. enjoy. i am also open to criticism on anatomy or errors
