This puppet is a traditional origami design that not only offers a project for you and your child, but it also brings loads of fun for both of you after the puppet is made. Origami Finger Puppet Tutorial by The Spruce Crafts I have a soft spot for all things feline, but I also appreciate fine art when I come across it. These origami cats combine the two beautifully and I couldn’t help but share them with you! Cat lovers will definitely be delighted!ġ. Today, I am swooned by these 15 tutorials on how to make an origami cat that is so adorable not to share with you all!ġ5 Easy Tutorials on How to make An Origami Cat Geological Survey and USGS-NPS Natural Resources Protection Program.My love affair with simple origami crafts continues! I love paper crafts - whether making a simple origami bookmark or a more complex paper box, origami is a great activity for me to do with my kids. Their continued studies at White Sands focus on the environmental conditions that allowed people to thrive in southern New Mexico during the Last Glacial Maximum and are supported by the Climate Research and Development Program | U.S. The research team included scientists from the USGS, Lawrence Livermore National Laboratory, the National Park Service, and academic institutions. Santucci, Daniel Odess, David Bustos and Matthew R. Reference: “Independent age estimates resolve the controversy of ancient human footprints at White Sands” by Jeffrey S. With three separate lines of evidence pointing to the same approximate age, it is highly unlikely that they are all incorrect or biased and, taken together, provide strong support for the 21,000 to 23,000-year age range for the footprints. Using this method, they found that quartz samples collected within the footprint-bearing layers had a minimum age of ~21,500 years, providing further support to the radiocarbon results. In addition to the pollen samples, the team used a different type of dating called optically stimulated luminescence, which dates the last time quartz grains were exposed to sunlight. “The pollen in the samples came from plants typically found in cold and wet glacial conditions, in stark contrast with pollen from the modern playa which reflects the desert vegetation found there today.” Additional Dating Methods Confirm Findings “Pollen samples also helped us understand the broader environmental context at the time the footprints were made,” said David Wahl, USGS research geographer and a co-author on the current Science article. In each case, the pollen age was statistically identical to the corresponding seed age. Importantly, the pollen samples were collected from the exact same layers as the original seeds, so a direct comparison could be made. The researchers used painstaking procedures to isolate approximately 75,000 pollen grains for each sample they dated.

Prints at base of trench, White Sands National Park. But our targeted methodology in this current research really paid off,” said Jeff Pigati, USGS research geologist and co-lead author of a newly published study that confirms the age of the White Sands footprints. “The immediate reaction in some circles of the archeological community was that the accuracy of our dating was insufficient to make the extraordinary claim that humans were present in North America during the Last Glacial Maximum. In 2021, scientific dating results from footprints found at White Sands National Park in New Mexico began a global conversation that sparked public imagination and incited dissenting commentary throughout the scientific community as to the accuracy of the ages. Two new lines of evidence support the 21,000 to 23,000-year age estimate of the footprints first described and dated in 2021.

Fossilized footprints in White Sands National Park sparked a scientific debate.
