Comparitive Forelimb Muscle Attachments - Ventral

The ventral forelimb muscle attachment sites in crocodylians, Anhanguera, and a corvid. The attachments in Anhanguera are inferred from muscle scars, and comparison with crocodylians and birds.

The Structure of a Pterosaur

Here's something I've been working on for quite some time: a multi-layered diagram of all the structural elements of a pterosaur - basically, the things that give them their shape.

You can find the full version, with a still image, an interactive version, and a higher-res video at palaeontography.

It's also up at YouTube, if you want to vote for it, or whatever people do on YouTube.
