This "wiggle-matching" technique can lead to more precise dating than is possible with individual radiocarbon dates.

The fossils include unique species of fish that had never been found in the area before. The discovery is reshaping views on California geology with the possibility of extinct islands.
The Cerutti Mastodon site is a paleontological and possible archeological site in San Diego County, California. In 2017, broken mastodon bones at the site were dated to around 130,700 years ago. The bones were found with cobblestones displaying use-wear and impact marks among the otherwise fine-grain sands.
