One of the factors that often gets overlooked in depictions or accounts of preservation is the effect that bacteria have, not only in destroying the tissue but also in preserving it through biomanipulation of the microclimate, precipitation of minerals on the soft tissue or producing a microbial film to glue an organism to the bottom of an environment long enough to be covered by sediment. (Gab et. al. 2020, Lin et. al. 2020, Janssen et. al. 2022) Determining the role of microbes in fossilization and the microbes responsible for it is both an achievable and important step in understanding the rapidity and process of fossilization. Experiments would include finding microbes that occur naturally in depositional environments that can change the chemical composition of the surrounding environment to balance the conditions needed for the preservation of the organism before it decays or is completely consumed, potentially by the same microbes. The goal of these experiments would be to observe and document the effect that the bacteria would have not only on the preservation process of the organic material but also the microbes’ effects on the surrounding sediment and matrix, comparing the results to known soft tissue preservation. This could be used to estimate the upper and lower time limits for the preservation of organic material. As well as the environments in which the organisms died and were buried. Due to the wide overlap of disciplines in play, it would be suggested that at least three people collaborate on these experiments, having specialties in organic or inorganic chemistry, microorganisms, and geology or fossils.
