Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

Acta Zoologica, Volume 107, Issue 4, Page 409-431, October 2026.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Reevaluation of the formation of spiral coprolites [PDF]

, 1985
—The type D valvular intestine of the extant elasmobranch Scyliorhinus canicula produces fecal ribbons that coil spirally within the colon. Spiral fecal masses are expelled from the body without distortion.

Prehistoric Medicinal Plant Usage: A Case Study from Coprolites

, 1992
Identifying medicinal plant usage from the prehistoric record is problematic due to the preservation of such information, and the lack of conclusive evidence provided through dietary and non-dietary assemblages.

Evidence for the continental origin of Pliocene deposits in the central Baja California peninsula, Mexico, and implications for controls on biodiversity

Sedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.
ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, Volume 309, Issue 9, Page 2424-2441, September 2026.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Plant taxa identified in upland moa coprolites from Euphrates Cave.

, 2012
N/A: non-angiosperm taxa unable to be detected by DNA primers used in this study. DNA taxa are nearest matches in Bayesian analysis, and presented as number of coprolites in which the taxa occurred.

Evaluating Rapid Extraction Methods for Recovering Ancient DNA From Archaeological Sediments

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
A modified Amicon‐based rapid DNA extraction protocol outperformed other rapid methods, recovering short DNA fragments from mock sediments within ~3 h. Application to archaeological sediments successfully recovered amplifiable DNA from ancient taxa. This rapid, portable, non‐hazardous approach establishes a premise for more informed sampling in time ...

Sedimentary Ancient DNA Tracks Multi‐Kingdom Ecosystem Reorganizations Following Sequential Human Land Use at Crawford Lake

Molecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Crawford Lake has an exceptional stratigraphic record that began recording biannual (varved) sedimentation in the lake basin ~750 years ago, preserving evidence of shifting cultural zones and agricultural practices, from Late Woodland Period Indigenous agriculturalists to the impacts of industrialization during the late 19th century.
