Invertebrate Trace Fossils

Invertebrate trace fossils include thin burrow tracks, various examples of social insect colonies, the ichnites (tracks) of  Octopodichnus (spiders) and Paleohelcura (scorpions), organic trails, gyrochorte trails and perhaps crustaceans (crayfish)?

     Burrows at Waterhole Canyon, Page, Arizona.   According to Rubin and Hunter, USGS, the
    corkscrew burrows resemble the borrows of some modern crustaceans.  I assume they mean
     some type of crayfish but it is hard to understand their occurrence with the present day image of
    the Navajo Sandstone ecosystem.

Social Nests

                                Worms?                                        Ants?   Termites or what?  Note that the burrows
                                                                                    start down at the cyclic crossbedding boundaries.
                                                                                    These burrows may have been created each year
                                                                                    during the rainy season?
