Although not fraud specifically, one could also mention Charles Lyell's spurious "geological dating" of strata presentation to the Royal Society, which relied on the circular reasoning of fossils being used to date rocks based on the length of time required for them to fit into a theory of evolution!

While not outright fraud, it is irrational and self-serving to "teach" as fact Lyell's method of dating(still employed and taught as reliable today).

Well there you go. They are reliable, as far as they go. But they are augumented by at least fifty independent measures of age.
