Imaging of Jurassic fossils from the Talbragar Fish Bed using fluorescence, photoluminescence, and elemental and mineralogical mapping.

open access: yesPLoS ONE, 2017
The Talbragar Fish Bed is one of Australia's most important Jurassic deposits for freshwater fishes, land plants and aquatic and terrestrial insects. The site has yielded many well preserved fossils, which has led to the formal description of numerous ...

Trace fossils in Upper Carboniferous' rocks of Velebit mountain (Ričice) [PDF]

open access: yes, 2011
Fosilni tragovi (ihnofosili) su geološki zapisi biološke aktivnosti. Tragovi kretanja se razlikuju od tjelesnih fosila, koji su fosilizirani ostaci dijelova tijela organizama.

Separation and Valorization of Chlorine From Tail Gas Streams

open access: yesAngewandte Chemie International Edition, EarlyView.
A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

Palaeoecological significance of the trace fossil Circulichnis Vyalov, 1971 from the Carboniferous of the Donets Basin, Ukraine

open access: yesGeologija
The ichnogenus Circulichnis Vyalov is a horizontal a ring- or ellipse-shaped burrow and/or locomotion trace of an unknown producer, most likely an annelid or a “worm”, preserved on the bedding plane. This ichnogenus is known over a wide

Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Autobiographical Trace Fossils

open access: yes, 2012
Ephemeral islands, petrified raindrops, volcanic dust from Pompeii, a shared birthday with a volcano. Certain geological processes have a way of evoking a more personal response to the idea of geological time. What does a time span of 300,000,000 years actually mean?

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.
