The division of food space among mammalian species on biomes

open access: yesEcography, Volume 2025, Issue 10, October 2025.
Understanding how species' ecological partitioning functions across biomes is fundamental to macroecology and conservation biology. Here, we examine the global distribution of dietary strategies in terrestrial mammals, focusing on how biome specialization modulates trophic diversity and structure at a broad geographical scale.

Functional morphology and biomechanics of an ontogenetic series of the Triassic cynodont Brasilodon quadrangularis and bite performance in the sister taxon of Mammaliformes

open access: yesPalaeontology, Volume 68, Issue 5, September/October 2025.
Abstract The Upper Triassic Santa Maria Supersequence in Brazil has yielded numerous cynodont species, including derived probainognathians, which are relevant for understanding the cynodont–mammal transition. One of these cynodonts is Brasilodon quadrangularis, considered to be the sister taxon to Mammaliaformes due to a suite of apomorphic features in

Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

open access: yesPalaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.
