I'm not sure I understand the question. The fossils were deposited in chronological order, obviously. The "linear progression" I was referring to is the idea that dinosaur A evolved into dinosaur B evolved into birdlike dinosaur C evolved into dinosaurlike bird D evolved into a bird. It's not that straightforward--or, rather, there might have been such a lineage, but the chances of finding fossils of A, B, C, and D are slim. Maybe A was the common ancestor of A1, A2, and A3, and A3 was a common ancestor of birds but we only find fossils from A1. And maybe A1s survived past the time D showed up, so we actually have birdlike fossils that are older than the fossils we have of an earlier species. One longtime participant in these threads had a nice clade diagram that showed how this worked--maybe somebody knows where to find it. Whatever--the point is that asking to see every stage of scapular development from dinosaur to bird is probably asking for too much.
(And knowing the age of a fossil bassed on what layer it was found in; and knowing the age of the layer by what fossils are found in it; Is pure circular reasoning.)
Fortunately, there's a lot more to it than that. Courtesy of Coyoteman's home page, a little primer on dating:

But I generally post data of that kind anyway, as other posters and perhaps many lurkers are still willing to learn.

You’re sure of htis how?
[[dinosaur A evolved into dinosaur B evolved into birdlike dinosaur C ]]
And you’re positive these weren’t all three uniquely created fully formed creatures of different KINDS hhow?
[[Whatever—the point is that asking to see every stage of scapular development from dinosaur to bird is probably asking for too much.]]
Perhaps- but showing a dino with a scapula and one without is expecting far too much in regards to believing the two are related, and that the one evolved into the other.
As for the radiometric dating- look into the problems with all the methods used, they are not insignificant- beyond approximately 7000- years, the systems used rely on pure speculation and are forced to either ignore or explain away with yet more assumptions all the dates that didn’t fit- not impressed with dating methods that rely on nothign but assumptions and which keep changing- many times by supposedly billions of years.
