Journey to two world-famous fossil sites in the middle Miocene
Barstow Formation: one locality yields upwards of 50 species
of fully three-dimensional, silicified freshwater insects, arachnids,
and crustaceans that can be dissolved free and intact from calcareous
concretions; a second Barstow Formation district provides vertebrate
paleontologists with one of the greatest concentrations of Miocene
mammal fossils yet recovered from North America--it's the type
