Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

Boreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

Mesozoic wildfires: distribution and importance for global events [PDF]

, 2012
The present paper summarizes the issues related with occurrence and distribution of wildfires in the Mesozoic. The main focus is put on occurrence of palaeowildfires during the Mesozoic global events, including Permian-Triassic (P/T), Triassic-Jurassic ...

Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

Journal of Anatomy, EarlyView.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...

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

Relationship between carina size and sternum morphology in birds reflects physical constraints of body size and flight style

Journal of Anatomy, EarlyView.
Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.
