Figure 10. A possible taphonomic process experienced by the Griffith specimen. (a) A section of trunk periderm dislodged and carried down a fast flowing stream; (b) the periderm stranded on a coarse sandbank and buried; (c) the sand compacted into rock, entrapping the resinous, long-lasting periderm, which eventually rotted and leached away, leaving an impressed void; (d) the rock eroded; (e) the impression of the outer surface of the periderm exposed on the bedrock surface; (f) bedrock broke down into gravel and loose rocks deposited in scree, one of which contained the impression.
