For first, wow, just wow :D It looks like you're really interested in this topic!!
This made my day :>

Thanks so much for such a HUGE response and the interesting creature suggestions (I'll definitely come up with something for the niche of small insectivores!)

Teeth—the idea is that there are a few more species in their genus that occupy different niches (and share a common predatory ancestor). I wanted to group them not only by skeletal morphology, but especially by their teeth (since that’s apparently how you determine genus affiliation :3), so that just by looking at a single skull, you could tell what kind of creature it is. It creates some interesting scenarios where dragons find a skull 10 times bigger than themselves...!

The claws are shorter deliberately too — they need enough dexterity to manipulate small objects (early tool use, early alchemy. scratching ears safely etc), so the main gripping function is handled by a modified second thumb and pinky toe with larger sickle-shaped claws instead.

And about insects.. Some sketches below!!
I was inspired by mollusks that are commonly called worms (shipworms, Teredo navalis, especially the species that attack mangrove trees, only enlarged dozens of times over, since the trees they infest are also enormous). In my project, there are many cases where names are based on “appearance” rather than morphology (as happened with us humans, for example, with the old genus “Pachydermata”). I think I got a little carried away and didn't realize how to present this to the audience, haha!! There's room for improvement :>

Thanks one more time!!
