Albuquerque, NM, August 6, 2012 - Discovered in the 1920s near Farmington, New Mexico, Alamosaurus was the last American brontosaur. This huge plant eater browsed in the forests that covered northwestern New Mexico just before the extinction of the dinosaurs, 66 million years ago. Today, Alamosaurus remains a somewhat elusive dinosaur. No complete skulls or skeletons have yet been discovered, and we know this dinosaur from only isolated teeth, vertebrae, parts of the shoulder and hips and some limb bones.
In 1978, a nearly complete foot was collected by a University of Arizona field crew and transferred to the New Mexico Museum of Natural History and Science in 2005.
On August 11, 2012, visitors to the Museum can view this foot for the very first time as part of Dinosaur Century: 100 Years of Discovery in New Mexico.
Born in 1889, John Reeside was a geologist and a native of Baltimore, Maryland. He spent his career working for the U.S. Geological Survey and was well-known for his studies of Cretaceous ammonites. In 1921, Reeside was mapping the coal fields of northwest New Mexico. It was on this expedition, that he discovered part of the shoulder and hip of a huge sauropod dinosaur near Ojo Alamo. That same year, Smithsonian paleontologist Charles Gilmore named this dinosaur Alamosaurus.
Prior to this discovery, North American sauropods were known only from the Jurassic and Early Cretaceous periods. Alamosaurus, however, was found in rocks of latest Cretaceous age. Alamosaurus continues to be the last known North American sauropod, about 40 million years younger than any previously known species.
Come see it all at Dinosaur Century: 100 Years of Discovery in New Mexico, only at the New Mexico Museum of Natural History & Science.
