Isotopic palaeoecology (δ¹³C) of three faunivores from Late Pleistocene of the Brazilian intertropical region

Mammal Taphonomy in a Cave Deposit From Quaternary of Brazil

“…In the F3 cave assemblage, most bones with tooth marks are assigned to consumption after the animals' death, which could imply necrophagy during this period of food scarcity. Probably this scavenging was made by S. populator (Dantas et al, 2020) and P. troglodytes (Berta, 1989;Dantas et al, 2021), the predators that lived closer to F3 cave (Araújo-Júnior and Porpino, 2011;Araújo-Júnior et al, 2017a). It is important to mention that food stress was not exclusive to drought.…”

Record and paleoecological insights of a sub‐adult specimen of Smilodon populator Lund, 1842 found in a cave in Bahia, Brazil

“…Based on this technique, some authors (e.g. Prevosti & Martin, 2013;Prevosti & Schubert, 2013;Bocherens et al, 2016;Dantas et al, 2020Dantas et al, , 2022a have inferred that S. populator may have been a pack hunter, exploring both open and closed environments, including giant mammals such as giant ground sloths and proboscideans in its prey options, but preying more on moderately large mammals such as horses and camelids, and occasionally acting as a scavenger.…”

Stable isotope analysis evidences dietary changes in toxodontids (Mammalia, Notoungulata) across the Neogene-Quaternary from Argentina

“…Concerning this, dental evidence (i.e., hypsodontia, which has traditionally been related to grazing habits in open grasslands, and tooth enamel microstructures that demonstrate increased resistance) suggests consumption of abrasive vegetation (Bond et al, 1995;Townsend & Croft, 2008;Cassini et al, 2011;Braunn et al, 2021); although some authors proposed that hypsodonty is not always associated with a grazing habit (e.g., Feranec, 2003;DeMiguel et al, 2008DeMiguel et al, , 2015Townsend & Croft, 2008). In recent decades, isotopic studies focused on the late Cenozoic fauna of South America have become increasingly frequent (e.g., Domingo et al, 2012Domingo et al, , 2020Dantas et al, 2013Dantas et al, , 2020Dantas et al, , 2022Bocherens et al, 2016;Pansani et al, 2019;Sanz-Pérez et al, 2022, 2024Varela et al, 2023), although still, many questions remain. In this context, the number of works that include representatives of Toxodontidae is low, and most of them are limited to the Pleistocene genus Toxodon (e.g., Lopes et al, 2013;da Silva et al, 2019;Pansani et al, 2019;Gomes et al, 2023;Varela et al, 2023).…”
