The presence of purported fossil forests in the geological record have occupied the attention of creationists ever since they began to publish scholarly articles in the 1970s and 1980s in secular journals on the topic of the Yellowstone fossil forests. Nothing has appeared in secular journals by creation scientists on the general topic of fossil forests since that time. Creationism's focus on the Yellowstone "fossil forests" has faded into the past as far as field research goes. In the meantime, secular scientists have published scores of studies on purported fossil forests in the last four decades. The central issue among creationists is whether any purported fossil forests are truly in situ, or autochthonous. To help resolve this issue a list of criteria has been developed from a creationist standpoint to identify what is in situ. This can have profound implications for the establishment of Flood models.
