Theres 2 ways to make a binder. Theres my friends way, which involves copying and pasting things from the internet, and that works sometimes, but for me, theres too much information and it takes too long to find what youre looking for. For my way, I make each page with a template like:
Physical Description
Range (time range of when it lived)
environment
behavior (mode of life, stuff like that)
and extra.
For each order (or class or suborder), put some information about when the group as a whole lived, anatomy, behavior, and stuff like that.
