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

open access: yesInternational 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

open access: yesPalaeontology, 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.
