Systematic utility of the phytosaur post‐dentary mandibular region

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract Phytosaurs, crocodile‐like archosaurs from the Late Triassic, are known for their unique skull shape, whereas their mandibles are poorly studied. Two‐dimensional (2D) geometric morphometric (GM) analysis is commonly used on dinosaurs and mammals.

Geomorfología y reconstrucción paleoambiental

Estudos do Quaternário / Quaternary Studies, 2000
Uma das questões mais actuais do nosso tempo é, sem dúvida, a da Mudança Climática. Porém geralmente não se leva em linha de conta que o clima é mutável por natureza, independentemente da actividade humana. Os estudos geomorfológicos são de grande ajuda na reconstrução paleoambiental.

Cuon Versus Canis: A Comparative Guide to the Morphological Distinction of Postcranial Bones and Its Archaeo‐Paleontological Implications

International Journal of Osteoarchaeology, Volume 35, Issue 5, Page 263-283, September/October 2025.
ABSTRACT The genera Cuon and Canis are part of the carnivore guild during the late Middle and Late Pleistocene in Europe. However, most identifications in archaeo‐palaeontological contexts are made on cranial and dental elements as these are taxonomically the most diagnostic anatomical regions.

Written in bones: palaeoclimate histotaphonomic history inferred from a complete Megatherium skeleton preserved in the Atacama Desert

Palaeontology, Volume 68, Issue 4, July/August 2025.
Abstract A nearly complete and relatively well‐preserved skeleton of the giant ground sloth Megatherium sp. in the hyperarid core of the Atacama Desert reveals how climate related taphonomic processes drastically transformed these remains over time.

Physical analysis and inverse methods applied to archaeological FIRE replications on ATACAMA desert soils, northern Chile

Archaeometry, Volume 67, Issue 3, Page 625-641, June 2025.
Abstract Physical analysis of in situ fire experiments on soils are useful for the estimation of subsurface thermal diffusivity, which is affected by factors such as water, heterogeneity and heating conditions. To address the uncertainties due to these factors, a new data‐processing procedure based on inverse methods was developed and experimentally ...
