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 ...
Tests of these tiny marine creatures form diatomite, and some of their organic remains persist as the high organic carbon content of parts of the formation (when conditions are right, these organic remains form petroleum reservoirs). South of the Santa Ynez Mountains, the ocean was deeper and the formation consists of finer muds and clays.
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 ...
The discovery this month of six human bodies and dozens of sets of cremated remains stored illegally in a San Francisco Bay Area warehouse has led to a daunting task: to reunite them with their ...
A view of Los Angeles covered in smog. Pollution in California relates to the degree of pollution in the air, water, and land of the U.S. state of California.Pollution is defined as the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a faster rate than it can be dispersed, diluted, decomposed, recycled, or ...
Microplastics have been found in historic soil samples for the first time, according to a new study, potentially upending the way archaeological remains are preserved.
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]
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 ...
