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]
California was a region of geologic upheaval during the Mesozoic, including both Mountain formation and volcanism. The Sierra Nevada began forming at this time. Mesozoic California included areas of both marine and terrestrial environments. The local seas were home to a variety of marine invertebrates and marine reptiles.
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.
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 ...
The Chemehuevi knew the caves as "the eyes of the mountain" due to their easily spotted dual entrances located on the side of the mountain. The caverns are named after Jack and Ida Mitchell, who owned and operated the caves from 1934 to 1954 as a tourist attraction and rest stop for travelers on nearby U.S. Route 66 .
Bog bodies are human remains which have been discovered in peat bogs around the world. They have been preserved naturally to varying degrees due to the specific conditions of peat bogs. Despite their natural preservation, these remains are sensitive to deterioration after being removed from their original locations.
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 ...
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.
