It's OK. I tried to find something, but I think i kept going in circles and ending up back where I started! I do recall the basic sizes in relation to other objects and such like, so that's not so bad.
Oh yeah, is it just the species I have to add dates and stuff, or for everything? If so then I reckon my paper might be swamped by dates! I've been trawling through classes, families etc.
