Not at all, just that the reefs are not bioherms, and there is a need to
consider models other than the accepted dogma, especially if you are going
to try to reinterpret the whole world.

No, only to point out that the prevaling paradigm can blind workers to the
data. In these cases, the earlier workers had assumed they were reefs on
the basis of the presence of fossil corals and the general reef-like shape
of the mounds. They were wrong.
