* Actually, I didn't really expect geologists to have data on what fossils are found in strata that do not appear anywhere on the surface.Lloyd, I'm hoping this doesn't sound too spoil-sporty, but I put together an extensive powerpoint presentation a couple years ago including images intended to present the kind of info you are looking for. Hundreds of hours yielded little satisfactory data... the fact is, this type of information just isn't known!
* So, in my illustration above, the fossils would be unknown for the most part. However, wherever strata are exposed to view, and mountains and the Grand Canyon etc probably expose the greatest numbers of strata, there is probably data somewhere that shows what fossils appear in each stratum in those places.
* Do you know where to find such data? I'll try to look at Allyn's and everyone's links shortly to see if they already have the answer.
* Also, I'm sure there's probably fairly detailed data on Geological Cross Sections throughout much of the world somewhere. Do you know where to get such data, or do you have it from your coursework and could we access it?
* There's quite a bit of data on the 12 mile deep hole in Russia. Do you know if oil drilling engineers generally have kept data on the strata encountered while drilling? If so, that may be how many geological cross sections where mapped.
* I believe that a fairly thorough compilation of such data could tell us approximately how the strata were laid down and what the continents looked like before and after each stratum was laid down.
* The largest mammal that supposedly lived in the age of dinosaurs was said lately to have been I think about 20 inches long.
* My hope is that we can get better clues that suggest whether dinosaurs lived in the age of humans and other mammals. It seems that there's already a number of tantalizing clues, but I suspect that it would not be hard to increase such data considerably.
