El Gran Intercambio Biótico Americano: una revisión paleoambiental de evidencias aportadas por mamíferos y aves neotropicales [PDF]

, 2013
Tradicionalmente, se ha considerado que la formación del istmo de Panamá (durante el Plioceno hace 3 Ma) facilitó el movimiento de especies entre Sudamérica y Norteamérica. Este proceso ecológico y evolutivo denominado Gran Intercambio Biótico Americano (

Huge Miocene Crocodilians From Western Europe: Predation, Comparisons with the “False Gharial” and Size [PDF]

, 2019
As shown here on the basis of bitten teeth, the diet of the huge, lower to early upper Miocene Tomistoma lusitanica included some of the largest contemporaneous, terrestrial mammals, including adult or senile gomphotheres (Gomphotherium angustidens). One

Discovery of a Pleistocene megafaunal assemblage in a cave in Sierra de El Abra, San Luis Potosí, Mexico

Revista Mexicana de Ciencias Geológicas
The Calera cave system in San Luis Potosí, Mexico, with a large Pleistocene megafaunal assemblage is described. Hundreds of fossil bones have been found throughout the 1324 m of mapped galleries.

Exceptionally preserved extracellular bone matrix proteins from the late Neogene proboscidean Anancus (Mammalia: Proboscidea)

PalZ, 2021
In an exceptional preservation state, bones conserve the entire pattern of extracellular bone matrix proteins over thousands or sometimes even millions of years.

A new Mammutidae (Proboscidea, Mammalia) from the Late Miocene of Gansu Province, China [PDF]

, 2016
The "Yanghecun specimen", a proboscidean specimen represented by a mandible from Miocene of China and previously described as Gomphotheriidae, is here reviewed and described as a new genus and species of Mammutidae: Sinomammut tobieni.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

American Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Climate‐driven ecological stability as a globally shared cause of Late Quaternary megafaunal extinctions: the Plaids and Stripes Hypothesis

Biological Reviews, Volume 94, Issue 1, Page 328-352, February 2019., 2019
ABSTRACT Controversy persists about why so many large‐bodied mammal species went extinct around the end of the last ice age. Resolving this is important for understanding extinction processes in general, for assessing the ecological roles of humans, and for conserving remaining megafaunal species, many of which are endangered today.

Legacy of the Lost and Pressure of the Present: Malagasy Plant Seeds Retain Megafauna Dispersal Signatures but Downsize Under Human Pressure

Ecology Letters, Volume 28, Issue 9, September 2025.
Using structural equation models, we show that Malagasy assemblages with higher human pressure have smaller maximum seed sizes, especially through downsizing of extant frugivores. Furthermore, among assemblages with ‘mega‐seeded’ plants (i.e., seeds that cannot be swallowed by any extant Malagasy frugivore), larger seed sizes are associated with larger

The last Iberian gomphothere (Mammalia, Proboscidea): Anancus arvernensis mencalensis nov. ssp. from the earliest Pleistocene of the Guadix Basin (Granada, Spain)

, 2014
This work describes a new finding of Anancus arvernensis ̶ a maxilla fragment that preserves M2 and M3 ̶ from the earliest Pleistocene (c.a. 2.5-2.4 Ma) at the Fonelas SCC-3 site (Cuenca de Guadix, Granada, Spain).

New proboscidean material from the Siwalik Group of Pakistan with remarks on some species

Paléobios, 2021
Over the years a diverse assemblage of proboscidean remains has been recovered from the Lower to Upper Siwalik Subgroups of Pakistan and India. This article reports newly discovered dental material of tri- and tetralophodont proboscideans that includes ...
