Ceramic micropalaeontology: the analysis of microfossils in ancient ceramics [PDF]

open access: yes, 2007
Microfossils can be a common component of ancient ceramic artefacts. Their analysis in this unusual context is a little-known, yet promising cross-disciplinary application of micropalaeontology.

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

The Northernmost Occurrence of the Tropical-Subtropical Brittle Star Ophiocoma (Echinodermata, Ophiuroidea) from a Late Cretaceous Rocky Shore in Southern Sweden

open access: yesTaxonomy, 2023
In spite of considerable progress during the last few years, the fossil record of the ophiuroids, or brittle stars, is still poorly known, especially with respect to taxa restricted to specific environments.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

On the survivability and detectability of terrestrial meteorites on the moon [PDF]

open access: yes, 2008
Materials blasted into space from the surface of early Earth may preserve a unique record of our planet's early surface environment. Armstrong et al. (2002) pointed out that such materials, in the form of terrestrial meteorites, may exist on the Moon and

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Proterozoic microfossils from the sedimentary rocks of the Lappajärvi impact crater [PDF]

open access: yesBulletin of the Geological Society of Finland, 1990
The Proterozoic microbiota of acritarchs is reported from the siltstone deposit of Lappajärvi. Diversity is low, with sphaeromorphs dominating the taxa, which also includes some coenobial and ovoidal specimens and a fragment of filament.

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).
