Reconstructing the Evolution of North American Gomphotheres (Mammalia, Proboscidea) through Craniomandibular Characters [PDF]

open access: yes
The family Gomphotheriidae is the “waste basket” of proboscidean groups. Widely accepted as paraphyletic, gomphotheres are characterized by bunolophodont molars and extreme morphological variability.

Diversity of the fossil gomphotheres from South America [PDF]

open access: yesHistorical Biology, 2022
The contemporary mammalian communities of South America were defined by the rise of the Isthmus of Panama and by the deep climatic oscillations during the Pleistocene. Gomphotheres are a conspicuous group of North American immigrant mammals that came to South America during the late Pliocene and did not survive the great megafauna extinction ...

Did the climate changes cause the extinction of the Late Pleistocene gomphotheres in South America? [PDF]

open access: yesZoologia (Curitiba)
A global wave of megafauna extinctions occurred between 50,000 and 10,000 years ago, impacting numerous large continental mammals that are crucial to ecosystem dynamics.

A new elephantoid dental specimen from the Miocene of Kruševac basin in Central Serbia [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2018
Elephantoid cheek teeth from the late Early and Middle Miocene of Europe frequently display mixtures of bunodont and zygodont features, making their taxonomical attributions difficult and subjective.

The "Tambla" (Humuya) Gomphothere (Honduras): The first report of fossil vertebrates in Central America

open access: yesRevista Geológica de América Central, 2011
In 1858, American geologist Joseph LeConte published the first scientific report of vertebrate fossils (mastodon, bison and horse) from Central America a brief record of a "mastodon bed" near the old village of Tambla in Honduras. In 1859, American archaeologist Ephraim George Squier also mentioned these fossils, illustrating a lower jaw fragment with ...

Frugivory and seed dispersal in the Cerrado: Network structure and defaunation effects

open access: yesBiotropica, Volume 55, Issue 4, Page 849-865, July 2023., 2023
We investigated the Cerrado seed dispersal network and the potential impacts of defaunation on it by performing a systematic literature review. The Cerrado network has a heterogeneous structure, slightly nested and considerably modular, and is dominated by generalist species.

Empirical examples demonstrate how relational thinking might enrich science and practice

open access: yesPeople and Nature, Volume 5, Issue 2, Page 455-469, April 2023., 2023
Abstract Interdependent relationships among humans and nature often go overlooked, delaying better environmental, social and public health outcomes. Emerging approaches have emphasized thinking through relationships, which we call ‘relational thinking’. Threads of relational thinking have matured in areas such as anthropology and Indigenous scholarship,

Tooth marker of ecological abnormality: The interpretation of stress in extinct mega herbivores (proboscideans) of the Siwaliks of Pakistan

open access: yesEcology and Evolution, Volume 12, Issue 11, November 2022., 2022
Enamel hypoplasia is a tooth marker of ecological abnormality which can also be used in fossil animals to evaluate the likelihood of extinctions. The Siwalik paleoenvironment is being tried to assess by using teeth of the fossil proboscideans. Abstract Climate affects living ecosystems and defines species physiology.

Giant dwarf crocodiles from the Miocene of Kenya and crocodylid faunal dynamics in the late Cenozoic of East Africa

open access: yesThe Anatomical Record, Volume 305, Issue 10, Page 2729-2765, October 2022., 2022
Abstract We describe two new osteolaemine crocodylids from the Early and early Middle Miocene of Kenya: Kinyang mabokoensis tax. nov. (Maboko, 15 Ma) and Kinyang tchernovi tax. nov. (Karungu and Loperot, 18 Ma). Additional material referable to Kinyang is known from Chianda and Moruorot. The skull was broad and dorsoventrally deep, and the genus can be

Taxonomic and palaeobiological implications of a large, pathological sabretooth (Carnivora, Felidae, Machairodontinae) from the Lower Pliocene of South Africa

open access: yesPapers in Palaeontology, Volume 8, Issue 5, September/October 2022., 2022
Abstract We describe the most complete postcranial remains of a pathological, large‐bodied sabretooth from the Lower Pliocene site of Langebaanweg ‘E’ Quarry (South Africa). The skeleton consists of hind limb and vertebral elements that exhibit distinctive exostoses, osteophytes and eburnation.
