Deep-sea Ordovician lingulide brachiopods and their associated burrows suggest an early colonization of proximal turbidite systems

open access: yesScientific Reports, 2023
Trace fossils from Ordovician deep-marine environments are typically produced by a shallow endobenthos adapted to live under conditions of food scarcity by means of specialized grazing, farming, and trapping strategies, preserved in low-energy ...

Discovery of trilobite trace fossils from the Early to Middle Cambrian, Tabas Block, Central Iran [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2017
Early to Middle Cambrian successions exposed at the Shirgesht area, Tabas Block of central Iran has yielded a high diversity and abundant ichnofossils with arthropod trackways. These trace fossils contain diverse ethological patterns, including furrowing

Mammillichnis monstrum isp. nov., a new sea anemone trace fossil from the Carboniferous of the Donets Basin, Ukraine

open access: yesGeo&Bio, 2022
A new ichnospecies Mammillichnis monstrum isp. nov. (Domichnia) is described from turbidite sandstone in the upper part of the Mospyne Formation (late Bashkirian, Early Pennsylvanian) of southern Luhansk Oblast, eastern Ukraine.

Multiple-Rusophycus assemblage from the Parnaíba Basin (NE Brazil) reflects trilobites as tracemakers and molting behavior

open access: yesFrontiers in Ecology and Evolution, 2023
Trilobites inhabited all environments of Paleozoic seas, ranging from estuaries to continental slopes, and were globally distributed. Although their functional morphology and phylogenetic relations are established by well-preserved body fossils, the ...

The swimming trace Undichna from the latest Devonian Hangenberg Sandstone equivalent of Morocco

open access: yesSwiss Journal of Palaeontology, 2021
Trace fossils occur in several strata of the Devonian and Carboniferous of the eastern Anti-Atlas, but they are still poorly documented. Here, we describe a fossil swimming trace from strata overlying the Hangenberg Black Shale (correlation largely based

Stratigraphic and sedimentological aspects of ichnofabric analysis

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2015
Trace fossils are one of the paleontological groups that could be used for solving complex geological problems. Trace fossils represent the sedimentological structures, produced by living organisms in the mass of sediment.

Comment on “Bilaterian Burrows and Grazing Behavior at >585 Million Years Ago” [PDF]

open access: yes, 2013
Pecoits et al. (Reports, 29 June 2012, p. 1693) describe bilaterian trace fossils and assign them an Ediacaran age based on the age of a granite interpreted as intrusive.

Trilobite expansion into estuarine environments during the Ordovician radiation [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
Trilobites have traditionally been considered fully marine. Through the integration of ichnological, palaeobiological and sedimentological datasets within a sequence-stratigraphic and strati­graphic palaeobiology framework, we challenge this assumption.
