Dinosaur footprints and other ichnofauna from the cretaceous Kem Kem beds of Morocco. [PDF]
PLoS ONE, 2014 We describe an extensive ichnofossil assemblage from the likely Cenomanian-age 'lower' and 'upper' units of the 'Kem Kem beds' in southeastern Morocco.

First known trace fossil of a nesting iguana (Pleistocene), The Bahamas.
PLoS ONE, 2020 Most species of modern iguanas (Iguania, Iguanidae) dig burrows for dwelling and nesting, yet neither type of burrow has been interpreted as trace fossils in the geologic record.

Gyrochorte “highways” and their environmental significance in shallow-marine sediments [PDF]
Acta Palaeontologica Polonica, 2020 The reworking of a trace by a subsequently following organism represents a so-called sequorichnial behavior and leads to formation of a “burrowing highway”. Burrowing highways occur more frequently than assumed in the fossil record.

The trace fossil Zoophycos from the Silurian of Estonia [PDF]
Estonian Journal of Earth Sciences, 2015 Trace fossils of the ichnogenus Zoophycos have been described for the first time from the Silurian of Baltica. They occur in Llandovery pure limestones of middle Estonia and in Ludfordian argillaceous limestones and early Pridoli crinoid grainstones of ...

Is the middle Cambrian Brooksella a hexactinellid sponge, trace fossil or pseudofossil? [PDF]
PeerJ, 2023 First described as a medusoid jellyfish, the “star-shaped” Brooksella from the Conasauga shale Lagerstätten, Southeastern USA, was variously reconsidered as algae, feeding traces, gas bubbles, and most recently hexactinellid sponges.

Animal–substrate interactions preserved in ancient lagoonal chalk
Scientific Reports, 2022 Trace-fossil assemblages reflect the response of the benthos to sets of paleoenvironmental conditions during and immediately after sedimentation. Trace fossils have been widely studied in pelagic shelf and deep-sea chalk deposits from around the globe ...

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

The complex case of Macaronichnus trace fossil affecting rock porosity
Scientific Reports, 2021 Bioturbation is an important factor for reservoir quality due to the modification of host rock petrophysical properties (i.e., porosity, permeability, and connectivity). However, there is no predictable relationship between bioturbation and its effect on

Malformations in Late Devonian brachiopods from the western Junggar, NW China and their potential causes [PDF]
PeerJ, 2022 Although malformations are found in both extant organisms and the fossil record, they are more rarely reported in the fossil record than in living organisms, and the environmental factors causing the malformations are much more difficult to identify for ...
