"...since the vast majority of sedimentary rocks were laid down by what science calls "A mass extinction event..."

Ummm, no. That's not what geologists or the geologic record says at all. The majority of rocks are thought to have been deposited slowly over time with only a minor component being from catastrophic events.

It could easily be the wrong dating has been applied to the layer these fossils were discovered.

No, the stratigraphy and ages of the rock record is well understood from thousands of radiometric dates of the appropriate method (e.g. uranium-lead, potassium-argon, etc.) from around the world. The possibility of a "whoops, wrong dating method!" being applied is virtually zero, not to mention that scientists don't rely on just a single method but dozens of methods that overlap in time range to double check their work.

The entire seafloor is modern, not ancient, as your favourite theory would suggest it should be.
Notice something odd about that? It doesn't fit in with what you'd expect from your favourite theory. Could it be your favourite theory is wrong? It sure sounds like it.

Why the mention of Catastrophic Plate Techtonics? It sure sounds like someone is trying to make light of a major catestrophic event. These can make entire continents move at the speed of about 2 m/s. Does that fit in with your favourite theory?
