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.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Interpreting a Legacy Fossil Assemblage Excavated From Waribruk (New Guinea II Cave), GunaiKurnai Aboriginal Country, Snowy River National Park, Southeastern Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

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 ...

A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

open access: yesIntegrative 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 ...

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.

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa 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.

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
