Animals in a Cenote
Artdaily [Mexico], Nov 4, 2010‎
Four complete skulls and jaws of a species extinct in America,
Arctotherium, that lived during the Pleistocene and disappeared 11,300
years ago, were found by sub aquatic archaeologists in the bed of a
cenote in the Yucatan Peninsula, Mexico. These are the only specimens of
their type found until now in this region of the country, and add up to
the list of Prehistorical fauna located inside this kind of water
bodies, which before glaciations were dry caves. Guillermo de Anda
Alanis declared that the remains were located in a submerged cavern
between the towns of Sotuta and Homun, in Yucatan, at 40 meters depth.
Bones were dispersed in a 120 meter diameter surface, and it has been
estimated that they could correspond to a family of bears, since the 2
adult skulls belonged to a male and a female, while the other 2 skulls
did not reach their full development. They were all from the same
species. The archaeologist indicated that besides the mammals' remains,
5 ancient human bone remains, still to be dated, were located 30 meters
away from the bears, but it is still unknown if they are related.

Researchers discover baby sauropod tracks
PhysOrg.com [USA], November 1, 2010
Staff at the Morrison Natural History Museum have again discovered
infant dinosaur footprints in the foothills west of Denver, Colorado,
near the town of Morrison. Dating from the Late Jurassic, some 148
million years ago, these tracks were made before the Rocky Mountains
rose, when Morrison was a broad savanna full of dinosaurs. The fossil
tracks represent infant sauropods, according to discoverer Matthew
Mossbrucker, the museum's director. Sauropods are giant, herbivorous
long-necked dinosaurs, sometimes known as "brontosaurs." The sauropod
Apatosaurus was first discovered in Morrison in 1877. As long as three
school buses parked end to end, and weighing as much as eight Asian
elephants combined, Apatosaurus is the largest dinosaur found in the
Denver metro area.

Riches of prehistoric bones unearthed at Snowmass site
The Denver Post, 11/06/2010
Perhaps the only thing a crew of scientists digging up prehistoric bones
at a Snowmass Village reservoir can be sure of is that they don't know
what will turn up next. "Five species in three days. I am jazzed,"
gushed Kirk Johnson, vice president of research and collections and
chief curator at the Denver Museum of Nature & Science, during a news
conference Friday morning at the Base Village conference center. The
tally includes at least one Columbian mammoth, evidence of five
mastodons, the bones of two ice-age bison, a small deerlike animal that
has yet to be identified, and a humerus, or upper arm bone, of a giant
ground sloth that stood up to 12 feet tall. The discovery of the five
mastodons was particularly noteworthy: Traces of only three mastodons
had ever been found in the state. "I'm proposing they change the
(town's) name to Snowmasstodon Village," Johnson told The Associated
Press.
