Quantitative ichnology: a novel framework to determine the producers of locomotory trace fossils with the ichnogenus Gordia as a case study

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

Putative hydroid symbionts recorded by bioclaustrations in fossil molluscan shells: a revision and reinterpretation of the cecidogenus Rodocanalis

Papers in Palaeontology, Volume 9, Issue 2, March/April 2023., 2023
Abstract The fossil record yields a peculiar phenomenon in different kinds of molluscan shells: bioclaustrations formed around (epi)symbionts during growth of the hosts' shell margin. Four morphologies, two of them formerly considered bioerosion traces, are here united in the parataxonomy of bioclaustration structures under the revised cecidogenus ...

Feeding habits of the Middle Triassic pseudosuchian Batrachotomus kupferzellensis from Germany and palaeoecological implications for archosaurs

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022
Abstract Bite traces on fossil bones are key to deciphering feeding ecology and trophic interactions of vertebrate past ecosystems. However, similarities between traces produced by different carnivorous taxa with similar dentitions, and misidentifications due to equifinality, hinder confident identifications of the bite makers.

Bioerosion and palaeoecological association of osteophagous insects in the Maastrichtian dinosaur Arenysaurus ardevoli

Lethaia, Volume 54, Issue 5, Page 957-968, December 2021., 2021
Bioerosions produced by the osteophagous diet of animals that fed on dinosaur bones are very scarce in the European fossil record. Herein we present bioerosion on hadrosaurid remains from the Maastrichtian Tremp Formation of the Pyrenean Basin, which is only the second such case recorded from the Iberian‐Occitan Plate besides a sauropod from the ...

Exploring confocal laser scanning microscopy (CLSM) and fluorescence staining as a tool for imaging and quantifying traces of marine microbioerosion and their trace‐making microendoliths

Journal of Microscopy, Volume 284, Issue 2, Page 118-131, November 2021., 2021
Abstract Microscopic organisms that penetrate calcareous structures by actively dissolving the carbonate matrix, namely microendoliths, have an important influence on the breakdown of marine carbonates. The study of these microorganisms and the bioerosion traces they produce is crucial for understanding the impact of their bioeroding activity on the ...

Invertebrate zoogeomorphology: A review and conceptual framework for rivers

WIREs Water, Volume 8, Issue 5, September/October 2021., 2021
Invertebrates affect the transport of sediment in rivers but are often overlooked due to their small size. Diverse behaviors result in significant effects on fluvial geomorphology. Abstract Invertebrates are important sediment engineers, making up for their small body size with abundance and behavioral diversity.

Taming an ichnotaxonomical Pandora's box: revision of dendritic and rosetted microborings (ichnofamily: Dendrinidae)

European Journal of Taxonomy, 2017
Dendritic and/or rosetted microborings in calcareous and osteic skeletal substrates have a diverse trace fossil record, spanning most of the Phanerozoic, whereas the ichnodiversity of comparable bioerosion traces produced in modern seas is rather limited.
