Biostratigraphy: stratigraphy based on fossil content. Biozone: layer of rock characterized by fossil content. Chlorophyll: green pigment found in plants. Chronostratigraphy: stratigraphy based on geological time. Cyanobacteria: microorganisms with chlorophyll that produce oxygen on photosynthesis.
Diagenesis: physical and chemical processes that operate on sediments after burial.
Exoskeleton: external skeleton of an animal.
Golden spike: physical point in a section equivalent to an instant in geological time marking the base of a stratigraphic unit.
Infaunal: living within the sediment.
Konservat-Lagerstätten: deposits containing exceptionally preserved fossils.
Konzentrat-Lagerstätten: deposits containing numerous fossils. Lagerstätten: deposits containing numerous and/or exceptionally preserved fossils.
Lithostratigraphy: stratigraphy based on rock characteristics. Pelagic: living in open water (floating or swimming).

This is common knowledge that disaster is everywhere. Its in the streets, its inside your campuses, and it can even be found inside your home. The question is not whether we are safe because no one is really THAT secure anymore but whether we can do something to lessen the odds of ever becoming a victim.
