...ANDREW M.W. LAWFIELD; RON K. PICKERILL Abstract A transitional Scoyenia – Mermia ichnocoenose from the Saint John River, Fredericton, New Brunswick, Canada, is dominated by elements of the Mermia ichnofacies, with traces comparable to Curvolithus , Helminthopsis , Gordia , Spirophycus , and Lockeia...

... and, accordingly, the Scoyenia and Mermia ichnofacies can be seen, at least in some sense, as taphofacies sensu Bromley & Asgaard (1991) . The Mermia ichnofacies characterizes finegrained sediments that occur in well-oxygenated, low-energy, permanently subaqueous zones of lacustrine systems ( Buatois &...

This inference is supported by documentation of atypical Mermia-type assemblages herein with moderate to very high ichnodiversity and facies...

.... This tubificid-formed graded bedding could be recognized in the rock record through careful analyses of grain-size distributions that distinguish biogenic reworking from physically graded beds. Ichnologically, this occurrence corresponds to the broad conditions defined by the Mermia Ichnofacies, but is yet...

... deposits are dominated by nonspecialized grazing trails, simple feeding traces, arthropod trackways, and fish trails. They are typical of freshwater environments and represent examples of the Mermia and Scoyenia ichnofacies. However, the local presence of acritarchs indicates sporadic marine influence...

... ichnofauna differs significantly from the conventional marine shelf ( Cruziana ), slope ( Zoophycos ), and basin plain ( Nereites ) ichnofacies. Two elements ( Gordia , Helminthopsis ) are typical of the (fresh) lacustrine Mermia ichnofacies ( Buatois and Mángano, 1995 ); others will surely be discovered...
