Abstract

We review the initial development of Bacterial Paleontology in Mongolia and present some electron microscopic images of fossil bacteria in different stages of preservation in sedimentary rocks. Indeed bacterial paleontology is one the youngest branches of paleontology. It has began in the end of 20th century and has developed rapidly in recent years. The main tasks of bacterial paleontology are detailed investigation of fossil microorganisms, in particular their morphology and sizes, conditions of burial and products of habitation that are reflected in lithological and geochemical features of rocks. Bacterial paleontology deals with fossil materials and is useful in analysis of the genesis of sedimentary rocks, and sedimentary mineral resources including oil and gas. The traditional paleontology is especially significant for evolution theory, biostratigraphy, biogeography and paleoecology; however bacterial paleontology is an essential first of all for sedimentology and for theories sedimentary ore genesis or biometallogeny

Highlights

Bacteria or microbes preserved well as fossils in various rocks, especially in sedimentary rocks alike natural substances
The recent electronmicroscopic studies of rocks varying both in chemical composition and age prove that fossilized microorganisms can be practically found in almost all sedimentary rock
Bacterial fossils are the remains of animals or plants that are preserved in rocks, that bacteria are neither plants nor animals

Summary

Introduction

Bacteria or microbes preserved well as fossils in various rocks, especially in sedimentary rocks alike natural substances. Many specialists of the 19th century claimed that there is a tremendous role of bacteria in the formation of the sedimentary mineral resources, like phosphorite, bauxite, iron ores, oil, hydrocarbon, petroleum gas, gold, sulfide, sulfur and sulfate, etc. Mongolian bacterial fossils from Precambrian and Cambrian sedimentary rocks and bedded phosphorite were examined using a Zeiss EVO50 SEM with an Oxford INCA microanalyzer (Energy 350) at the Paleontological Institute of the Russian Academy of Sciences were published repeatedly (Zhegallo et al, 2000).
