Inside a gastropod shell there is a hexagonal pattern that sort of looks likes Paleodictyon, but I think this fossil formed in too shallow of water for Paleodictyon to occur, but I am not sure. Its on a 3" post-it note for scale. (There is also a nice Pterotheca to the left!)These arguments suggest that xenophyophores could have origins stretching back into the late Neoproterozoic. There have been two concerted attempts to establish a fossil history for the xenophyophores. The first was by Swinbanks (1982), who reinterpreted the trace fossil Paleodictyon (early Cambrian to Recent) as a tubular, reticulated ...
