The gomphotheres were a diverse and widespread group of proboscideans occupying Eurasia, North America, and South America throughout the Neogene. Their decline was temporally and spatially heterogeneous, and the gomphotheres ultimately became extinct

In 2008 a rich accumulation of vertebrate bones and teeth was discovered in a small tributary drainage to Big Cypress Creek near the town of Hockley in Harris County, Texas. The fossils were recovered from sandy sediments of fluvial origin, intersper

The Columbian mammoth (Mammuthus columbi) and the American mastodon (Mammut americanum) have traditionally been considered to have been ecologically distinct, with mammoths often characterized as cosmopolitan grazers or mixed feeders and mastodons as

Analyses into the feeding ecology of Mammut americanum have reconstructed this extinct proboscidean as a forest-dwelling browser that thrived across North America during the Pleistocene. However, the level of variability in mastodon diet that may hav

A mammoth skeleton found at the Newton Site, a kettle lake 15 km southeast of Towanda, Pennsylvania, has been referred to Mammuthus columbi on the basis of its high, narrow skull. However, the specimen's thin enamel (1.3–1.8 mm) and moderately high

The input of massive amounts of carbon to the atmosphere and ocean at the Paleocene–Eocene Thermal Maximum (PETM; ∼55.53 Ma) resulted in pervasive carbonate dissolution at the seafloor. At many sites this dissolution also penetrated into the unde
