  Gomphothere - Wikipedia, the free encyclopedia
The Gomphotheres are a diverse group of extinct elephant-like animals (proboscideans) that were widespread in North America during the Miocene and Pliocene epochs, 12-1.6 million years ago.
Gomphotheres differed from elephants in their tooth structure, particularly the chewing surfaces on the molar teeth.

The kinds of proboscideans present in Florida in the late Miocene were the gomphotheres.
Gomphotheres are extinct, but were the most widespread and diverse group of proboscideans.

A gomphothere is a four-tusked relative of mastodons which are in turn distantly related to modern elephants.
This specimen was found on a Sierra College field trip in west central Nevada in 1987.
Horses, camels, beaver, sabertooth cats, dog-bears and rhinoceros shared the ecosystem with the gomphothere.

 Amebelodon - Wikipedia, the free encyclopedia
Amebelodon is a member of a diverse group of primitive proboscideans called gomphotheres, a group that also gave rise to the modern elephants and their close relative the mammoth.
Like other typical gomphotheres, Amebelodon possessed two sets of tusks, two upper tusks and two lowers that extended from the lower jaws.
Because of the superficial resemblance of the lower tusks to shovels, Amebelodon is commonly referred to as a "shovel-tusked" gomphothere (this same term is also applied to other gomphotheres with flattened lower tusks, specifically Platybelodon, Serbelodon, and Torynobelodon).

Museum, Wuhan, Hubei Province, China]] The Gomphotheres are a diverse group of extinct elephant-like animals, (proboscideans).
In North America, rodents, large mastodonts and gomphotheres, and opossums continued successfully, while hoofed animals (ungulates) declined, with camel, deer and horse all seeing populations recede.
Elephants, gomphotheres and stegodonts were successful in Asia, and hyraxes migrated north from Africa.

Paul Remeika points to the 3.5-million-year-old footprint of an extinct, elephantlike gomphothere.
Smack in the middle of all of this, obliterating the trail of the small predators, is a single print of a much larger animal –; easy to overlook because it is so unfamiliar.
Gomphotheres were elephantlike ancestors of mammoths, according to George Jefferson, head paleontologist for the Colorado Desert District of California State Parks.

He determined this fossil, USNM 16644, to be the remains of a gomphothere, an early ancestor of the elephant, named Gompotherium obscurum.
Judging form the age of strata in which it has been found elsewhere, this gomphothere lived sometime between 15 to 5.2 million years ago.
The fossils recovered from rained-washed exposures of clay include a horse jaw, three horse teeth, a camel jaw, a fragments of a gomphothere tooth and skull, and fragments of a jaw from a deer-size artiodactyl called _Prosynthetoceras francisi_.

The postcranial elements are attributed to a gomphothere because in general they are shorter and more massive than the same elements of a mammoth.
On the ulna, the anconeal process is not pronounced and the posterior tip of the olecranon process overhangs the shaft as typical in American mastodons (Olsen, 1972).
Molars with single trefoils, the possession of three lophids in the ml and rn, and the absence of accesory conules in the valleys also suggest that the material is a gomphothere.

 Ramage: April 2006
As naturalist Connie Barlow writes in her book The Ghosts of Evolution (New York: Basic Books, 2000), certain species of plant - such as the humble but delicious avocado - have been discovered to be anachronisms, adapted to thrive in the symbiotic presence of another species that has since vanished from the earth.
The avocado, with its rich flesh and gigantic seeds, is haunted by the ghosts of the giant sloth, gomphothere, and toxodon: Pleistocene mega fauna capable of swallowing the fruit whole and dispersing the pits.
In the absence of such creatures, the future of the wild avocado is uncertain - it has lost its context, and must either evolve, find new partners, or perish.

The fossils belong to six giant ground sloths (Eremotherium sp.) and four Gomphothere mastodon (Cuvieronius tropicus) found in La Trinidaita dated at 45,000 14CBP, and eight giant ground sloths from Llano Hato, dated at 47,000 14C BP.
The Gomphothere mastodon is also a giant mammal of the Ice Age, a sort of elephant.

Through the first half or so of the last ice age, three different families of proboscideans lived in the northern Chihuahuan Desert: gomphotheres, mastodons, and mammoths.
The huge, complex teeth of mammoths are ideal for withstanding the rapid wear caused by grazing on grasses.
Mastodons have relatively small, simple teeth great for crushing soft leaves, while gomphothere teeth are just a little more complex for slightly harsher foods.
