Actually, I'm considering adding real photos of fossils as well as artistic reconstructions of what the living animal may have looked like.

First, hello to anybody who remembers me from the .com and .org sites! It's been a while... Anyway, I see geologic time scale charts that look like this: and I want to create another one, but much longer so I can show more details. I've already gotten a binder and put pages in it to create a "book" timeline. Here it's opened to the page from 75 to 100 million years ago, with ages labelled. As in the first timeline, I want to put pictures of life that existed at the time. Does anybody know good resources that will give tell me what types of life existed at a given point in time, so I can find appropriate photos to put in there? I know I can look at the Wikipedia pages for the different periods and go from there, but other places may be more helpful.

Pi is an interesting number, but it's not as mystical as you think. It probably does, but this has not been proven. There are lots of irrational (and indeed transcendental) numbers that do not contain every finite digit string. The simplest provable example is Liouville's constant 0.110001000000000000000001000... which has a 1 in the 1st, 2nd, 6th = 3!, 24th = 4!, etc. place and a zero elsewhere. This number is clearly irrational and can also be proven to be transcendental, but it clearly does not contain all our information in its decimal expansion.
