ossamenta: Picture of an owl from a Medieval manuscript (Medieval owl)
[personal profile] ossamenta
In the comments to the strangest animal bone-post, I mentioned bird quadrates. And since I doubt most readers will immediately get an image in their minds from that word alone, I thought I’d add a picture.

Photobucket
Quadrates from chicken (left) and duck (right). This bone attaches between the skull and the mandible in birds and reptiles.

The quadrate is one of those bones that are rarely illustrated, so when you find them it’s not easy to immediately attach them to a species or to a specific element group. Before I learned to recognise them for what they were, I often put them in the fish bones bag.

Here is a good photo of the quadrate in situ.


And in my hunt for cool zooarch blogs, I came across Zygoma, which mostly consist of very difficult mystery object posts. The reason I find them very difficult is that these specimens come from all over the world - it's not too difficult to identify the type of animal, but which of the 13 different otter species is the one in the photo? *tears hair*

The right bone is not a quadrate but a pterygoid (it is connected to the quadrate)
