alaüüriperiood
Alaüüriperiood refers to a geological time span characterized by specific rock formations and fossil assemblages. This period is typically identified and studied within the context of paleontology and stratigraphy, the scientific disciplines concerned with the history of life and the study of rock layers, respectively. The precise boundaries of the alauüriperiood are defined by the appearance and disappearance of certain key indicator species, or by distinct changes in the lithology of sedimentary rock sequences.
Fossils found within rocks dating to the alauüriperiood provide crucial insights into the evolutionary pathways and
