Late Cambrian arthropod trackways from the Potsdam Sandstone have been known since the 1850s. A site in Clinton County, New York, USA, exposes Protichnites in fine-grained, quartz-rich, rippled, micro-laminated Potsdam Sandstone. The study area includes evidence of microbial mat growth on the original surface where the trackways were produced. Ripple marks presumably underlie, and therefore were generated prior to, the microbial mat. Trackway preservation is variable over the outcrop and…

A trace fossil made by a walking crayfish or crayfish-like arthropod from the Lower Jurassic Moenave Formation of southwestern Utah, USA
A previously unstudied arthropod locomotory trace that comprises two widely spaced, thick, gently undulating paramedial impressions flanked externally by small, tapered to elongate tracks with a staggered to alternating arrangement is placed in a new ichnospecies, Siskemia eurypyge.
The “Plastotype Problem” in Ichnological Taxonomy
Abstract When naming ichnotaxa based on uncollectable trace fossils, the holotype is the actual ichnofossil in the outcrop, though some ichnologists identify the holotype as a replica (cast) held in

Hermit arthropods 500 million years ago
Cambrian intertidal sandstones of North America record early excursions of large animals onto tidal flats, where continuous microbial films served as preservational agents for surface tracks. Whereas
Trace fossils and bioturbation in peritidal facies of the Potsdam-Theresa formations (Cambrian-Ordovician), Northwest Adirondacks
The Cambrian-Ordovician Potsdam Sandstone, Theresa Formation, and Canadian correlatives in the St. Lawrence Lowlands preserve tide-dominated facies during the basal Cambrian transgression. Low
Wrinkle structures: Microbially mediated sedimentary structures common in subtidal siliciclastic settings at the Proterozoic-Phanerozoic transition
Sedimentary structures produced by microbial activity are well known from ancient carbonate facies, but little is known about equivalent microbial structures in ancient siliciclastic facies. Wrinkle
Stratigraphic and structural framework of the Potsdam Group in eastern Ontario, western Quebec and northern New York State
The presence of a major unconformity within the Potsdam Group is an important key to unlocking the geological history of this succession throughout its area of distribution in the Ottawa Embayment

Arthropods invade the land: trace fossils and palaeoenvironments of the Tumblagooda Sandstone (?late Silurian) of Kalbarri, Western Australia
The trace fossils of the Tumblagooda Sandstone (?late Silurian) of Kalbarri, Western Australia are spectacular in their variety and preservation. They provide a unique insight into the activities of
Systematic ichnology of the Mabou and Cumberland groups (Carboniferous) of western Cape Breton Island, eastern Canada, 2: surface markings
Carboniferous (Namurian-Westphalian A) strata of the Mabou and Cumberland groups outcrop extensively in western Cape Breton Island. As well as a diverse collection of burrows, trails, pits, and
Paleobiology of Climactichnites, an Enigmatic Late Cambrian Fossil
The trail of Climactichnites may constitute the work of an otherwise unknown phylum in the animal kingdom, and the proposed method of feeding, if correctly interpreted, is unique.
Exceptionally preserved Late Ordovician biotas from Manitoba, Canada
There are few body fossil biotas known from early Paleozoic accretionary shorelines, and very few examples of Ordovician soft-bodied assemblages. This study documents two recently discovered biotas
