Palaeoecology of Middle Devonian epizoans and their Paraspirifer hosts

open access: yesPalaeontology, Volume 69, Issue 2, 2026.
Abstract The Silica Shale brachiopod, Paraspirifer bownockeri, of Ohio and Michigan, USA, preserves a unique window into Middle Devonian communities, as individuals hosted numerous epibionts. Herein, we use qualitative and quantitative methods to test hypotheses regarding the palaeoecology of these brachiopod hosts and their epibionts.

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

open access: yesThe Anatomical Record, Volume 309, Issue 1, Page 5-32, January 2026.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Eating lizards: a millenary habit evidenced by Paleoparasitology

open access: yesBMC Research Notes, 2012
Background Analyses of coprolites have contributed to the knowledge of diet as well as infectious diseases in ancient populations. Results of paleoparasitological studies showed that prehistoric groups were exposed to spurious and zoonotic parasites ...

Geoarchaeological Investigation of Early Neolithic Lagoonal Fringe Landscapes in the Netherlands

open access: yesGeoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Coastal wetlands have historically been portrayed as too marginal for early crop cultivation during the Mesolithic–Neolithic transition due to their dynamic hydrology, low elevation, and poor drainage. However, growing evidence suggests that these environments played a crucial role in the spread of agriculture. We examined buried and submerged

Minimally Destructive Radiocarbon Dating of Bone

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 9, 15 May 2026.
ABSTRACT Rationale Bone is commonly used in radiocarbon dating in archaeology and other disciplines. Despite advances in collagen extraction protocols, the process remains destructive, requiring sawing, drilling or crushing of bone material. While non‐destructive approaches have recently been applied in ancient genomics and palaeoproteomics, no ...

Analysis of COI and ITS2 regions of DNA obtained from Paragonimus westermani eggs in ancient coprolites on Joseon dynasty mummies

open access: yesMemorias do Instituto Oswaldo Cruz, 2019
The genetic information of ancient Paragonimus westermani, the oriental lung fluke infecting over 20 million people worldwide, has not been thoroughly investigated thus far. We analysed genetic markers (COI and ITS2) of P.
