Reconciling diverse lacustrine and terrestrial system response to penultimate deglacial warming in southern Europe [PDF]

, 2015
Unlike the most recent deglaciation, the regional expression of climate changes during the penultimate deglaciation remains understudied, even though it led into a period of excess warmth with estimates of global average temperature 1–2 °C, and sea level

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Towards a process of translational palaeoecology: A practical guide to research co‐production

Ecological Solutions and Evidence
Palaeoecology has the potential to support practical conservation, offering a long‐term perspective to issues such as biodiversity loss, environmental restoration and peatland carbon storage.

Vegetation context and climatic limits of the Early Pleistocene hominin dispersal in Europe [PDF]

, 2010
The vegetation and the climatic context in which the first hominins entered and dispersed in Europe during the Early Pleistocene are reconstructed, using literature review and a new climatic simulation. Both in situ fauna and in situ pollen at the twelve

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

The fate of the homoctenids (Tentaculitoidea) during the Frasnian-Famennian mass extinction (Late Devonian) [PDF]

, 2006
The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals which are amongst the most abundant and widespread of all Late Devonian fossils.

“Grassland in a jar” – an ecological view of the archaeobotanical contents of vessels from two Lusatian Urnfield Culture settlements (Early Iron Age) in north-central Poland

Acta Palaeobotanica
During the archaeological exploration of two Lusatian Urnfield Culture settlements, dated to the Early Iron Age and located in north-central Poland, 11 well-preserved clay vessels filled with waterlogged botanical remains were discovered.

Eocene foraminiferal biofacies in Kutch Basin (India) in context of palaeoclimate and palaeoecology

Journal of Palaeogeography, 2019
The Eocene Epoch passed through multiple hyperthermal events and recorded highest temperatures in the Cenozoic. Very few studies from Eocene palaeotropical sites have recorded changes in shallow marine foraminiferal assemblages.

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
