Tectonics, Volume 43, Issue 1, January 2024.Abstract Ultrahigh‐pressure (UHP) rocks in North‐East Greenland lie within a larger region of high‐pressure Laurentian crust formed in the overthickened upper plate of the collision with Baltica. Coesite‐bearing zircon dates UHP metamorphism to 365–350 Ma, which formed at the end of the Caledonian collision as a result of intracontinental subduction ...

Miospores in givetian to lower frasnian sediments dated by conodonts from the Boulonnais, France [PDF]
Review of Palaeobotany and Palynology, 1980 Abstract The Calcaire de Blacourt and the lower part of the Schistes de Beaulieu exposed in the new railroad trench Caffiers-Ferques and in the Griset Quarry (Boulonnais, France) contain well-preserved miospore assemblages which have been previously described from continental beds in Scotland, Spitsbergen and the Canadian Arctic Islands.

Investigating a Devonian vertebrate assemblage with synchrotron microtomography of coprolites
Scientific ReportsFossilised faeces (coprolites) are a unique source of information as they record palaeontological evidence of animal behaviour (autecology) as well as interactions between extinct organisms and their environment (synecology).

Occurrence of subnormal size phenotype in the latest Eifelian/earliest Givetian boundary, Tibagi city, Paraná State, Brazil: taphonomic and paleosynecologic implications [PDF]
Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2010 Subnormal size phenotype of marine invertebrates is recorded at the interval Neo-Eifelian/eo-Givetian (Devonian). These fossils represent a relictual fauna that resulted from a biotic crisis.

Towards a palaeogeographical and sequential framework for the Givetian of Belgium
, 2009 This paper starts with a review of facies and reef morphologies from the Givet Group in the Ardenne area. Platform initiation and evolution are analyzed and related to external factors at a global scale (sea level changes, climate changes), at a regional scale (local subsidence, change in detrital supply) and to internal factors like organic ...

A New Genus of Lungfish from the Givetian (Middle Devonian) of Central Australia
Acta Palaeontologica Polonica, 2009 A new Dipterus-like lungfish, Harajicadipterus youngi, is described from the Givetian (Middle Devonian) Harajica Sandstone Member of central Australia. The material is comprised of five specimens representing the skull roof, orbital bones, tooth plates, operculo-gular bones, a partial pectoral girdle, centra and scales.
