Hemiauchenia [1] is a genus of lamine camelids that evolved in North America in the Miocene period about 10 million years ago. This genus diversified and entered South America in the Late Pliocene about three to two million years ago, as part of the Great American Biotic Interchange. The genus became extinct at the end of the Pleistocene.
Other groups of carnivorans did not arrive in South America until much later. Dogs and weasels appear in South America about 2.9 Ma ago, but do not become abundant or diverse until the early Pleistocene. [106] Bears, cats, and skunks do not appear in South America until the early Pleistocene (about 1 Ma ago or slightly earlier). [106]
At the time, Earth's continents were in a very different arrangement and were generally smaller than they are today. The southeastern part of the US was connected to South America and Africa and located in the polar latitudes of the southern hemisphere. The western states were located near the equator. [7]
Camelids were domesticated by early Andean peoples, [12] and remain in use today. Fossil camelids show a wider variety than their modern counterparts. One North American genus, Titanotylopus , stood 3.5 m at the shoulder, compared with about 2.0 m for the largest modern camelids.
Volcanoes were still erupting on the moon during Earth’s dinosaur age, new research suggests, much more recently than previously believed.. Three tiny glass beads that were collected from the ...
On March 20, at 3:45 pm Pacific Standard Time, a shallow, magnitude-4.2 earthquake centered below the volcano's north flank, [13] signaled the volcano's return from 123 years of hibernation. [14] A gradually building earthquake swarm saturated area seismographs and started to climax at about noon on March 25, reaching peak levels in the next ...
