And a good detailed article about how the geologic column is dated.
Oh my! We all so dumb & uninformbud we hadn't done none of us heard of no such evodate stuffs before. Where come you to find such overstonishing uptech thingys? We just alls thoughts "radiometric dating" was on the AM/FM Tram-Sister how to pick up chicks but couldn't never make it works for usses.

Of particular interest are 15.10 Dating sedimentary rocks, and 15.11 The geological timescale. Here you can read about the various ways that scientists date layers. Of course, Woodmorappe has omitted what is IMO the most obvious one: you can have igneous layers below and above sedimentary deposits. Radiometric dates for those will give you boundaries for the age of the sedimentary layers.

Given his qualifications, I wonder why Woodmorappe doesn't mention these things, as he must be aware of them. Strange, don't you think?

You also have not addressed the heart of his argument, mentioned in my post above. If you think you can lend some logic to it then you are welcome to try.
You must've missed the point that we're talking about the places that allegedly contain the "entire geological column". How evodates were obtained elsewhere isn't a concern here.

Now shoo! This thread doesn't need to be cluttered up with off-topic propaganda. We know you love your evodates, and I can list plenty of the methods by which they're obtained. One should also appreciate what an expensive undertaking it can be, when test after test after test must be run until the desired result is achieved. (I chuckle to think how many swift kicks those expensive machines must endure when frustration takes its toll.)
