The fossils are typically three-dimensional and, on occasion, exhibit internal anatomy. Due to the preservation of soft-tissue, the Barstow Formation has been identified as a Konservat-Lagerstätte deposit. The fauna was first recognized in 1954 by Allen M. Basset and Allison "Pete" R. Palmer. [6]
Generally speaking, human remains are best preserved in cool, dark, dry conditions while wrapped in acid-free (non-buffered) tissue and packing materials. [19] Corporeal materials should not be stored in or near any wood or in any containers which previously housed wood due to potentially increased lignin levels, which produce an acid that can ...
Contrary to popular belief, the tar pits don't contain dinosaur remains, as these were extinct before the pits formed. [27] The park is known for producing myriad mammal fossils dating from the Wisconsin glaciation. While mammal fossils generate significant interest, other fossils including fossilized insects and plants, and even pollen grains ...
Weathering is the source of most of the deterioration of archaeological sites. Wind, rain, freeze-thaw, and evaporation are extremely common and can cause erosion. Natural disasters, such as floods, fires, earthquakes, and volcanic eruptions, can cause the complete destruction of a site. [5]
Among the black bear remains from La Brea is the skull of a juvenile individual. Black bears from this time were larger than their modern relatives, but are relatively underrepresented in the La Brea fossil record. This might be due to their omnivorous diet, suggesting that the abundance of predators may be directly related to scavenging behavior.
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.
As a research biologist was trekking a remote area in California 25 years ago, they stumbled upon human remains. Initially, a coroner didn’t find any reason to think the man, whose remains were ...
In some cases microbes control the phosphatization, and the remains of the microbes that feed on the preserved tissue form the fossil. In other, the tissue itself is the source of phosphate and its phosphatized remains form the fossil. In the intermediate case the phosphatized tissue retains the impressions of the phosphatizing microbes. [1]
