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 ...
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 ...
Historically, the Aliso Canyon floor was occupied by wide and braided Aliso Creek, which changed course often and flowed in a wide and shallow channel. Although the creek through the canyon remains unchannelized, it has suffered a series of effects from increasing runoff and pollution. Upstream development which has resulted in increased runoff ...
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.

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 ...
It is estimated that only as little as one percent of the original skeletal material is preserved in radiolarian oozes. According to Dunbar & Berger (1981) [4] even this minimal preservation of one percent is merely due to the fact that radiolarians form colonies and that they are occasionally embedded in fecal pellets and other organic aggregates.
