Pollen diagram for upland moa coprolites from Euphrates Cave.

open access: yes, 2012
Pollen assemblages are plotted with cluster analysis tree of coprolites based on pollen assemblages, calibrated ages of radiocarbon dated coprolites, and organic content. Colouring defines coprolites sharing highly similar pollen assemblages.

Manure Fertilization Gives High-Quality Earthworm Coprolites with Positive Effects on Plant Growth and N Metabolism

open access: yesAgronomy, 2019
Humic substances (HS) are important soil components playing pivotal roles in guaranteeing long-term soil fertility. In this study, the chemical and biological properties of HS extracted from earthworm coprolites collected in soils subjected to different ...

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Combined visual and biochemical analyses confirm depositor and diet for Neolithic coprolites from Skara Brae

open access: yesArchaeological and Anthropological Sciences, 2020
Coprolites (fossilized faeces) can provide valuable insights into species’ diet and related habits. In archaeozoological contexts, they are a potential source of information on human-animal interactions as well as human and animal subsistence.

Multiproxy analysis of omnivore and herbivore coprolites: Inferences on Mid-Holocene dietary habits in Argentine Patagonia

open access: yes, 2021
Learning about past biological interactions is possible thanks to the study of trace fossils, such as coprolites found in archaeological sites. The multiproxy analysis of coprolites may provide evidence of direct and indirect consumption of diet items ...

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

open access: yesCladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Palynology and chronology of hyaena coprolites from the Piñar karstic Caves Las Ventanas and Carihuela, southern Spain

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 2020
This paper presents pollen analyses and radiocarbon dating on Crocuta coprolites from Las Ventanas (LV) and Carihuela (Car) Caves in southern Spain (Granada), with the aim of reconstructing the environmental conditions of these hominin sites.

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3137-3168, November 2026.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Coprolites, Paleogenomics and Bone Content Analysis

open access: yes, 2016
Coprolites are fossil scats and provide indirect witness of the activity of past animals of a given area, whether or not fossil bones of these animals are present in the site. The shape, size, inclusions and geo- and bio-chemical composition are criteria
