Students in New Mexico Find a Triassic Fossil Mystery
March 18 | CNJ Online

Students in a Mesalands Community College paleontology class field trip found a hip bone from an unidentified Triassic period creature that lived about 200 million years ago. Although the bone has some similarities with a coelophysis, it is thought to represent a previously undiscovered early dinosaur or proto-dinosaur.

New Age Estimate for the Grand Cayon?
March 7 | Reuters

University of New Mexico scientists say that the western portion of the Grand Canyon is much older than the currently favored age of about 6 million years. They base their revised age of 17 million years on uranium-lead isotope dating of mineral deposits found in caves from nine sites in the canyon’s walls.

Water Level Declines in the High Plains Aquifer
June 9 | USGS

USGS has released a fact sheet that contains interesting maps and data documenting water level declines in the High Plains Aquifer. This important aquifer underlies over 100 million acres in Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas and Wyoming. Water levels in the aquifer have been in decline since it was first tapped for irrigating crops. Enormous declines - often over 150 feet (pre-development to 2005) - have been measured in many areas. This is a short report in .pdf format and worth a look just to see the maps. Reference: USGS Fact Sheet 2007-3029, Changes in Water Levels and Storage in the High Plains Aquifer, Predevelopment to 2005.

Mammoths Wiped Out by Impact
May 17 | Canada.com

Sediments rich in iridium, fullerenes and other compounds associated with extraterrestrial impacts are found in lakes from New Mexico to Canada. These document that a large impact probably occurred about 12,000 years ago - corresponding to the extinction of the mammoths, mastodons and sloths that were once common in North America. It is at odds with the idea that these large mammals were hunted to extinction by humans.
