Denton does mention the ediacaran forms on page 161-162 but then on page 163
states, "Again, just as in the case of the absence of pre-Cambrian fossils,
no forms have ever been found in the pre-Cretaceous rocks linking the
angiosperms with any other group of plants." p. 163. The first phrase of
this statement is erroneous.
