AlpIce‐1: a database of geochronological and geomorphological constraints on Alps‐wide palaeoglacier fluctuations between the Last Glacial Maximum and the Holocene

Boreas, EarlyView.
The AlpIce‐1 database is the first compilation of published geomorphological and geochronological markers constraining build‐up, culmination and decay of glaciers from the Last Glacial Maximum through the Holocene across the entire European Alps. AlpIce‐1 integrates more than 4200 surface‐exposure and radiocarbon ages, homogenized, quality controlled ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Reflections on the Use of Ecological Attributes and Traits in Quaternary Botany

Frontiers in Ecology and Evolution, 2020
There has been an upsurge of interest and research activity in trait-based approaches in ecology, biogeography, and macroecology. I discuss if this upsurge has impacted Quaternary botany (the study of plant remains preserved in sediments).

Heterodonty in the teeth of the turiasaurian sauropod from Angeac‐Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches

Journal of Anatomy, EarlyView.
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

Environment of European Last Mammoths: Reconstructing the Landcover of the Eastern Baltic Area at the Pleistocene/Holocene Transition

Land
The Eastern Baltic area stands out as a unique location due to the finds of Europe’s youngest dated mammoth remains (12.6–11.2 ka cal BP). Our study explores the drastic climate and landcover changes during the extinction of these gigantic herbivores at ...

Studies in New Zealand Oligocene and Miocene Plant Macrofossils [PDF]

, 2021
<p>Assemblages of fossil leaves ranging in age from Upper Oligocene to Upper Miocene or Lower Pliocene have been examined from localities in Southland, Central Otago, the Dunedin area, the Buller region and Great Barrier Island. Nearly 200 form taxa have been recognized so far; of these 52 are figured and described and the remainder are included ...

Mid to late Holocene storminess and fire history on the Baltic coast of Latvia

Frontiers in Ecology and Evolution
Coastal peatlands are sensitive archives of past environmental change, preserving evidence of both atmospheric and surface disturbances. Here, we reconstruct Mid- to Late Holocene storminess and fire dynamics from a 330-cm peat sequence recovered from ...

Development of the late glacial Baltic basin and the succession of vegetation cover as revealed at Palaeolake Haljala, northern Estonia [PDF]

Estonian Journal of Earth Sciences, 2009
The 4.5 m thick Haljala sequence in North Estonia was studied to provide information on palaeoenvironmental changes between 13 800 and 11 300 cal yr BP.
