A new ascarid species in cynodont coprolite dated of 240 million years

open access: yesAnais da Academia Brasileira de Ciências, 2014
Cynodonts represent the transition from reptiles to mammals. They are classified as synapsids, or tetrapod animals with mammalian characteristics. We present here the finding of helminth eggs in a coprolite identified as of cynodont origin dated of ...

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.

Determining the impact of elemental composition on the long‐term survival of vegetable‐tanned leather in archaeological environments

open access: yesArchaeometry, Volume 67, Issue 5, Page 1394-1411, October 2025.
Abstract This research paper investigated whether elemental analysis can differentiate leather manufacturing from soil contamination and whether soil hydrology and elemental composition impact degradation of leather. Portable X‐ray fluorescence (pXRF) is a quick method for monitoring large‐scale changes and groupings of aggregate inorganic elemental ...

Does size matter? Morphological and content analysis of the coprolites from a Quaternary deposit in the Iberian Peninsula

open access: yesQuaternary Environments and Humans
Coprolites are very abundant in Quaternary deposits. However, they are often overlooked despite offering insights into both the surrounding environment and the species that produced them, particularly when skeletal remains are absent.

Synchrotron phase-contrast microtomography of coprolites generates novel palaeobiological data

open access: yesScientific Reports, 2017
Coprolites (fossil faeces) reveal clues to ancient trophic relations, and contain inclusions representing organisms that are rarely preserved elsewhere.

Effective dispersal of fern spore and the ecological relevance of zoochory

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2116-2130, October 2025.
ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.

Seedling mortality in two vulnerable tree species in the sacred groves of Western Ghats, South India [PDF]

open access: yes, 2005
Sacred groves form a significant component of the traditional conservation movement in many parts of the tropical world1. The Western Ghats, one of the two mega-diversity centers in India, is dotted with sacred groves, with the highest concentrations ...

First bone-cracking dog coprolites provide new insight into bone consumption in Borophagus and their unique ecological niche

open access: yeseLife, 2018
Borophagine canids have long been hypothesized to be North American ecological ‘avatars’ of living hyenas in Africa and Asia, but direct fossil evidence of hyena-like bone consumption is hitherto unknown.

PARASITES FROM HUMAN COPROLITES FROM MEXICO ZOONOTIC AND HUMAN PARASITES OF INHABITANTS OF CUEVA DE LOS MUERTOS CHIQUITOS, RIO ZAPE VALLEY, DURANGO, MEXICO. [PDF]

open access: yes, 2012
We present the first reconstruction of the parasitoses among the people of the Loma San Gabriel culture, as represented by 36 coprolites excavated from the Cueva de los Muertos Chiquitos in Durango, Mexico.
