Protichnites eremita Unshelled? Experimental Model-Based Neoichnology and New Evidence for A Euthycarcinoid Affinity for This Ichnospecies

  title={Protichnites eremita Unshelled? Experimental Model-Based Neoichnology and New Evidence for A Euthycarcinoid Affinity for This Ichnospecies},
  author={Joseph H. Collette and Kenneth C. Gass and James W. Hagadorn},
Abstract Protichnites eremita from the Cambrian Elk Mound Group of Wisconsin is reinterpreted based on new material and trackway experiments. Two new forms of P. eremita suggest that the discrete medial imprints of these traces could be produced by the segmented postabdomen of euthycarcinoids from the same deposit. Form 1 could have been produced by a pair of euthycarcinoids traveling together, like in limulid amplexus, where both individuals made imprints with their postabdomens. In this… 
A Unique Winged Euthycarcinoid from the Permian of Antarctica
This occurrence indicates that euthycarcinoids were able to adapt to life in temperate freshwater environments, while possible subaerial adaptations hint at an ability to breathe air.
A new Devonian euthycarcinoid reveals the use of different respiratory strategies during the marine-to-terrestrial transition in the myriapod lineage
New data provide additional support for amphibious lifestyle in euthycarcinoids and show that different respiratory strategies were used during the marine-to-terrestrial transition in the myriapod lineage.
First record of a xiphosuran trackway (Kouphichnium isp.) from the Jurassic of India
A 44 cm long trackway from the Kimmeridgian-Tithonian of the western Kachchh Basin represents the first evidence of the occurrence of members of the order Xiphosura in the Jurassic of India. The
The Strud crustacean fauna (Late Devonian, Belgium): updated review and palaeoecology of an early continental ecosystem
ABSTRACT Arthropods were the first known animals to colonise land habitats, with myriapods and arachnids having done so at least by the Silurian. Much later, several lineages of Pancrustacea
The prelude to continental invasion
The Cambrian shows no ichnologic evidence that true continental environments were colonized but rather indicates brackish-water colonization as well as excursions into subaerial coastal dune environments by animals able to survive temporary periods of desiccation.
A molecular palaeobiological exploration of arthropod terrestrialization
A molecular palaeobiological approach is implemented, merging molecular and fossil evidence, to elucidate the deepest history of the terrestrial arthropods and showed that a marine route to the colonization of land is the most likely scenario.
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.
Early Paleozoic colonisation of the land – evidence from the Tumblagooda Sandstone, Southern Carnarvon Basin, Western Australia.
The early Paleozoic Tumblagooda Sandstone outcrops principally in the vicinity of the Murchison River in Kalbarri National Park, Western Australia. It contains a great variety of trace fossils that


Three-Dimensionally Preserved Arthropods from Cambrian Lagerstätten of Quebec and Wisconsin
Abstract Three new types of arthropod are described from Cambrian intertidal lithofacies of the Elk Mound Group and St. Lawrence Formation of Wisconsin and the Potsdam Group of Quebec. These
Testing the ‘mass-moult-mate’ hypothesis of eurypterid palaeoecology
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
Abstract The large euthycarcinoid arthropod Mictomerus melochevillensis from the middle Cambrian-Furongian Potsdam Group of Quebec occurs as three-dimensional casts at the end of Cruziana- and
The early history and phylogeny of the chelicerates
When fossil taxa are considered, the limits of the Chelicerata become less well constrained, especially true of various problematic arthropods: fossils such as aglaspidids, chasmataspids, Sanctacaris Briggs and Collins, 1988 and other Burgess Shale-type arthropODs.
Between a rock and a hard place: arthropod trackways and ichnotaxonomy
These principles of ichnotaxonomy have been developed with arthropod trackways in mind, but it is hoped that they will be of more general utility.
A redescription of Chasmataspis laurencii Caster & Brooks, 1956 (Chelicerata: Chasmataspidida) from the Middle Ordovician of Tennessee, USA, with remarks on chasmataspid phylogeny
The type material of Chasmataspis laurencii from the Middle Ordovician of Sevier County, Tennessee, USA, is redescribed, and comparisons are drawn with recently discovered Devonian chasMataspidids from Scotland, Germany and Russia.
Synaustrus and the euthycarcinoid puzzle
Sternal pores in euthycarcinoids resemble coxal vesicles, though this conflicts with other morphological indications of aquatic habits, and the evidence presented here allies euthyCarcinoid with atelocerates, but they cannot be positioned higher than the stem-lineage of Atelocers.
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
