...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...

... Abstract At present, three continental archetypal ichnofacies are widely accepted: the Scoyenia, Mermia and Coprinisphaera ichnofacies. The last is present in palaeosols, and the first two occur in fluvio-lacustrine environments. Additionally, the Skolithos ichnofacies may be present...

... these lacustrine delta types. Lacustrine delta deposits contain trace fossils that can be ascribed to three different ichnofacies: a high-diversity occurrence of the Mermia ichnofacies in subaqueous delta front sediments, a low-diversity occurrence of Mermia ichnofacies in subaqueous marginal lacustrine 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...

Ichnofaunas are typically dominated by nonspecialized grazing trails ( Mermia , Helminthopsis , Helminthoidichnites ), simple feeding traces ( Treptichnus...

The traces of horseshoe crabs, shore crabs, sea slaters, and ostracods resembled the ichnotaxa Kouphichnium , Laterigradus , Pterichnus , and Mermia , respectively. Other experimental work has shown hermit crabs produce traces similar to Coenobichnus and our...

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...

Also, the strong seasonality of Cooking Lake should provide striking ichnological contrast with changing conditions. At Cooking Lake, chironomid larvae are the dominant bioturbators in water deeper than...

Two elements ( Gordia , Helminthopsis ) are typical of the (fresh) lacustrine Mermia ichnofacies ( Buatois and Mángano, 1995 ); others will surely be discovered...

... Carboniferous outcrops of eastern Kansas are said to be distinct from normal-marine trace-fossil assemblages and can be used to refine fluvio-estuarine intertidal facies.

Pollard and Hardy (1991) did not assign the traces to an ichnotaxon but stated the locomotor traces closely resembled Mermia isp., but without the distinctive looping found in that ichnospecies. The dimensions and patterns of these traces...
