The pollen and spores from the Paleoproterozoic Roraima Formation in South America has often been cited by creationists as evidence against the evolutionary interpretation of the fossil record. It has, however, received little interest from the scientific community, having been ignored altogether since the 1970s. Although the discovery was published in Nature, there were no subsequent articles dealing with it. The consensus seems to be that the microfossils represent a case of contamination. In the original article in Nature an additional objection was raised: since the sediment containing the microfossils is described as thermally metamorphosed, the pollen and spores should have also been affected by heat, but they are not. Since there has been a lot of discussion in the blogosphere and some creationists have requested our help, we decided to take a closer look at this particular case.
