Ichnotaxonomy as a science [PDF]
Annales Societatis Geologorum Poloniae, 2018 If ichnotaxonomy is to be scientific, then its results must be repeatable. While some ichnotaxa are identified consistently, others are not, suggesting that ichnotaxonomy is not a mature science. When researchers disagree on the identification of a specimen, it suggests that closer examination is needed: an intermediate stage in the scientific method ...

Rhizoliths and the Recognition of Plant and Microbial Trace Fossils
GeosciencesRecognizing a trace fossil as a record of organism–substrate interaction is well agreed upon, but some organisms and some interactions are not considered by some workers to be tracemakers or to have produced trace fossils.

Ichnotaxonomy of microboring traces in marine aphotic depths [PDF]
Geologia CroaticaMicroboring traces in carbonate skeletal fragments deposited in aphotic depths of the oceans are studied, evaluated, and described with respect to their marine ecology and palaeoecology as well as ichnotaxonomy. Sand-size deep sea sediment particles dredged from depths ranging between 600 and 3266 m of the Bermuda Pedestal, Central Atlantic Ocean, the ...

Triassic chirotheriid footprints from the Swiss Alps: ichnotaxonomy and depositional environment (Cantons Wallis & Glarus) [PDF]
Swiss Journal of Palaeontology, 2016 Autochthonous Triassic sediments of the Vieux Emosson Formation near Lac d’Emosson, southwestern Switzerland, have yielded assemblages with abundant archosaur footprints that are assigned to chirotheriids based on pentadactyl pes and manus imprints with characteristic digit proportions. Tridactyl footprints formerly considered as those of dinosaurs are

A review of large Cretaceous ornithopod tracks, with special reference to their ichnotaxonomy [PDF]
Biological Journal of the Linnean Society, 2014 Trackways of ornithopods are well-known from the Lower Cretaceous of Europe, North America, and East Asia. For historical reasons, most large ornithopod footprints are associated with the genus Iguanodon or, more generally, with the family Iguanodontidae.

Concepts in ichnotaxonomy illustrated by small round holes in shells [PDF]
Acta geológica hispánica, 1981 La clasificación de las pistas fósiles requiere un doble sistema de nomenclatura. El nombre de la pista fósil (ichnotaxon) está basado en la morfologia de la estructura, mientras que el taxon biológico representa la posicion filogenética que se interpreta del organismo causante.

Palaeontology, Volume 66, Issue 6, November/December 2023., 2023 Abstract Trace fossils record the interactions between organisms and their surroundings, and can therefore provide unique insights into the coevolution of trace makers and the environment. However, identifying the producers of trace fossils is challenging because different animals can create very similar traces and many ichnotaxa can therefore only be ...

Contourite channels – Facies model and channel evolution
Sedimentology, Volume 70, Issue 3, Page 611-644, April 2023., 2023 Abstract Despite the rise in published evidence of deep‐marine bottom current processes and associated deposits there are still very few documented outcrop examples. Herein are reported results of a contourite channel system related to the late Miocene palaeo‐Mediterranean Outflow Water in the Rifian Corridor, Morocco.

An abundant sea anemone from the Carboniferous Mazon Creek Lagerstӓtte, USA
Papers in Palaeontology, Volume 9, Issue 2, March/April 2023., 2023 Abstract Sea anemones (Actiniaria) are among the rarest of recognized fossil organisms, even rarer than jellyfish. Here we demonstrate that the most abundant fossil in the Pennsylvanian Mazon Creek Lagerstätte of Illinois, Essexella asherae, is an infaunal or semi‐infaunal anemone. Essexella is redescribed based on a taphonomic analysis of thousands of
