You might check your local library for Jennifer Clack's book, Gaining Ground. Dr Clack will tell you right off what you've just been told here - that it is not typically possible to say "this fossil individual was a descendant of that other one right there." Then, she goes on to write 300 pages or so of very information-dense, heavily illustrated text about Devonian critters. She whups the reader nearly to death with cleithrums and clavicles and with skulls with their post-parietals and ectopterygoids and ethmosphenoids, and on and on. But she also shows, repeatedly, how smooth sorts of changes occur between different fossils, and that these changes occur with advancing time as well as with the change of critters to look less ans less "fishy" and more and more "salamandery" or at least amphibian.
No, there's not much "proof," but dear me, there sure are a boatload of fossils that would be pretty durn tricky to explain in any manner other than that Clack uses: descent with modification.

Re: Pelycodus
but they could be referencing depth up from some datum level.
That's standard practice, as the present-day ground surface can be pretty cut up by erosion - in Wyoming, especially. The numbers make sense when you measure from a depositional surface, though.

Re: won't be here much for awhile
Happy reading, Christian. You might consider skipping Numbers and the first half of Joshua, though.

Re: horse evolution
3. The "ancient horse" is not a horse at all, it's a hyrax still alive in South America today.
This is wrong everywhere you look. Hyracotherium or "eohippus" isn't any more related to the modern hyrax than humans are. The hyrax is kin to elephants and manatees, instead. And they live in Africa and the Middle East, not South America. Pretty poor fact-checking, I would say.
