Importance of eDNA taphonomy and sediment provenance for robust ecological inference: Insights from interfacial geochemistry

open access: yesEnvironmental DNA
Retrieval of modern and ancient environmental DNA (eDNA) from sediments has revolutionized our ability to study past and present ecosystems. Little emphasis has been placed, however, on the fundamentals of the DNA–sediment associations in environmental ...

Taphonomy of Early Triassic fish fossils of the Vega-Phroso Siltstone Member of the Sulphur Mountain Formation near Wapiti Lake, British Columbia, Canada

open access: yesJournal of Palaeogeography, 2013
The taphonomy of fishes living in lacustrine environments has been extensively studied in both the laboratory and the fossil record; the taphonomy of marine fishes, however, is poorly known.

Revisiting the concept of entomotoxicology

open access: yesForensic Science International: Synergy, 2020
Until now, the term entomotoxicology has only been used in medico-legal sciences. However, entomotoxicology as a whole has a much wider scope and forensic entomotoxicology is just one of its branches.

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

open access: yesRoyal 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 ...

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

open access: yesActa 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 ...

Taphonomy of the fossil insects of the middle Eocene Kishenehn Formation [PDF]

open access: yesActa Palaeontologica Polonica, 2015
The lacustrine oil shales of the Coal Creek Member of the Kishenehn Formation in northwestern Montana comprise a relatively unstudied middle Eocene fossil insect locality.

Fish taphonomy and environmental inference in paleolimnology [PDF]

open access: yes, 1988
The contribution of fish studies to palaeoecology generally takes the form of (1) inference from analogies in modern fish faunas and (2) fish taphonomy--the pattern of death and dispersal of bones.

X-rays and virtual taphonomy resolve the first Cissus (Vitaceae) macrofossils from Africa as early-diverging members of the genus

open access: yes, 2022
Premise of the study: Fossilized seeds similar to Cissus (Vitaceae) have been recognized from the Miocene of Kenya, though some were previously assigned to the Menispermaceae.

The taphonomy of a micromammalian faunal assemblage from the Saldanha Bay Yacht Club : a contribution to the study of the South African west coast palaeoenvironments [PDF]

open access: yes, 2002
Bibliography: leaves 129-146.This thesis provides a broad outline of the effect of taphonomic and ecological processes on the accumulation and transformation of micromammalian faunal assemblages, and the importance of the signatures left behind by these ...

Decomposition in an extreme cold environment and associated microbiome—prediction model implications for the postmortem interval estimation

open access: yesFrontiers in Microbiology
IntroductionThe accurate estimation of postmortem interval (PMI), the time between death and discovery of the body, is crucial in forensic science investigations as it impacts legal outcomes.
