Análisis de contenido paleontológico en la Laguna Punzara

Abstract

Abstract:The research work on the potential of microfossils in the foothills of the Laguna Punzara reveals a low preservation of the same that can be due to several factors, such as the quality sampling, subsequent geological processes, unfavorable environmental conditions and the difficult to detect. The abundance of microfossils in certain horizons may be related to various causes, such as the age of the rock or sediment, the presence of organisms producers of organic matter, the deposition of sediments in an environment conducive to the formation of microfossils and their preservation over time. The study identifies and classifies 3 species of planktonic foraminifera, some of which are best preserved in deep, well-oxygenated marine environments. It is suggested that the preservation of the remains of the microfossils may be influenced by the water temperature and sea salinity at the time in which organisms lived. The presence of three specific species of microfossils is discussed, including Orbulina universa d'Orbigny, Globigerina nepentes Todd and Globorotalia fohsi peripheroacuta Blow & Banner, and the possible paleoenvironments in which they were deposited are indicated.
