An Amphibian was Moving Around during the Flood

Today I went over to LiveScience, and read an article about the fossilized body imprints of a Salamander like creature. This has huge implications for a Global Flood. This would mean that right when the geologic column was being "thrown down" by the flood, something was moving. Not only that, but this flooding didn't destroy the imprint. Think about it. A flood happens and is rapidly burying everything in sediment, yet this creature is moving, and moving right in the middle of the geologic column.
