Dinosaur Anatomical Terms

[Pachyrhinosaurus]

After reading some of the forums, I decided that a thread like this would be useful to all members here. I'll start off.
Epoccipital=The spikes or bumps on the outside of a ceratopsid's frill
Patagium=Skin flaps which form a wing or winglike structure.
Propatagium=Pterosaur patagium which runs from wrist to shoulder
Brachiopatagium=Pterosaur patagium stretching from the fourth finger to the hind legs
Nasal horn=Horn on the nasal area of a ceratopsid (paleoferroequine)
Postorbital horn=The horn above the eye (orbital) on a ceratopsid (paleoferroequine)
Parietosquasmosal frill=Bony margin on the head of a ceratopsian (paleoferroequine)
Squasmosals=Outer bones on a ceratopsid frill (paleoferroequine)
Parietal=Center bones of a ceratopsid frill (paleoferroequine)
Episquamosals=Epoccipitals on the outer edge of a ceratopsid frill (paleoferroequine)
Epiparietals=Epoccipitals on the top edge of a ceratopsid frill (paleoferroequine)
Thagomizer=Spikes found at the end of a stegosaur tail (Zopteryx)

Is there a technical term for ceratopsian nasal and brow horns?

Not that I know of. I was actually looking for the technical term for ceratopsian frills.

Nasal horn and postorbital horn.
The frill is the parietosquasmosal frill. Simply put the squasmosals are the outer bones and the parietal is in the center. I hope.
The epoccipitals are broken down as episquamosals (outer edge)and epiparietals(top edge)

Thagomizer:  Informal term for the tail spikes of stegosaurs

I added all the terms to the original post, giving credit to the poster.

Thagomizer:  Informal term for the tail spikes of stegosaurs

Yet it was used in Planet Dinosaur

And IIRC in formal literature as well.
