Nucleus preservation in early Ediacaran Weng'an embryo-like fossils, experimental taphonomy of nuclei and implications for reading the eukaryote fossil record

Interface Focus, 2020
The challenge of identifying fossilized organelles has long hampered attempts to interpret the fossil record of early eukaryote evolution. We explore this challenge through experimental taphonomy of nuclei in a living eukaryote and microscale physical ...

Survival of environmental DNA in sediments: Mineralogic control on DNA taphonomy

bioRxiv, 2020
Extraction of environmental DNA (eDNA) from sediments are providing ground-breaking views of the past ecosystems and biodiversity. Despite this rich source of information, it is still unclear which sediments favour preservation and why.

Minerals in the gut: scoping a Cambrian digestive system [PDF]

Royal Society Open Science, 2016
The Sirius Passet Lagerstätte of North Greenland contains the first exceptionally preserved mat-ground community of the Cambrian, dominated, in terms of abundance, by trilobites but particularly characterized by iconic arthropods and lobopods, some also ...

Taphonomy of Biosignatures in Microbial Mats on Little Ambergris Cay, Turks and Caicos Islands

Frontiers in Earth Science, 2020
Microbial mats are taxonomically and metabolically diverse microbial ecosystems, with a characteristic layering that reflects vertical gradients in light and oxygen availability.

Taphofacies and Stratigraphic Correlation of Devonian Outcrops in Northwestern Region of State of Paraná, Brazil

Terr@ Plural, 2021
The northeastern region of the state of Paraná, Brazil, is still little known in its paleontological and stratigraphic aspects. This work focused on Devonian outcrops located in Arapoti and Piraí do Sul and aimed at the recognition of sedimentary facies

A new subdisarticulated machaeridian from the Middle Devonian of China: Insights into taphonomy and taxonomy using X-ray microtomography and 3D-analysis [PDF]

Acta Palaeontologica Polonica, 2017
Machaeridians are an extinct group of armoured annelids, which are mainly known from isolated sclerites present from the Ordovician to the Permian. Based on articulated specimens with preserved soft-tissues and trace fossils, derived machaeridians are ...
