Lungfish diversity in Romer's Gap: reaction to the end‐Devonian extinction

, 2016
Romer's Gap, the interval following the end‐Devonian extinction event, has been described as a post‐extinction trough for vertebrates. It is a time roughly equivalent to the Tournaisian stage of the early Carboniferous and has been characterized by a ...

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, EarlyView.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions

Journal of Raman Spectroscopy, EarlyView.
Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).

An exceptionally preserved Late Devonian actinopterygian provides a new model for primitive cranial anatomy in ray-finned fishes

Proceedings of the Royal Society B: Biological Sciences, 2015
Actinopterygians (ray-finned fishes) are the most diverse living osteichthyan (bony vertebrate) group, with a rich fossil record. However, details of their earliest history during the middle Palaeozoic (Devonian) ‘Age of Fishes' remains sketchy.

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

PLANTS, PEOPLE, PLANET, EarlyView.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.
