Integrative Zoology, EarlyView.This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Flying ticks: anciently evolved associations that constitute a risk of infectious disease spread [PDF]
, 2015 Ticks are important vectors of emerging zoonotic diseases affecting human and animal health worldwide. Ticks are often found on wild birds, which have been long recognized as a potential risk factor for dissemination of ticks and tick-borne pathogens ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations
Acta Zoologica, EarlyView.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.

Sedimentology, EarlyView.ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Intrahepatic abscess secondary to retained stercolith, following laparoscopic appendectomy
Radiology Case Reports, 2023 Abscesses of the peritoneal cavity and in particular hepatic abscess due to stercolith retention are a rare complication of appendectomy. Their prevalence is likely to increase as laparoscopic appendectomies become more common.

The Depositional Record, Volume 12, Issue 2, April 2026.During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Recovering parasites from mummies and coprolites: an epidemiological approach
Parasites & Vectors, 2018 In the field of archaeological parasitology, researchers have long documented the distribution of parasites in archaeological time and space through the analysis of coprolites and human remains.
