Stromatolites, the most prevalent type of microbialites, are important fossils for comprehending the beginning and evolution of life and are prevalent in rocks older than 500 million years, which account for roughly two-thirds of the State.
What is Paleomicrobiology ?
The methodologies and key discoveries in this new area of study, which straddles anthropology, history, and microbiology, are presented in "Paleomicrobiology - Past Human Infections."
- Numerous unrelated health issues were present in his body, according to a paleomicrobiological examination of microbial ancient DNA (aDNA). In addition to having gallstones and hardening arteries, Tzi had parasitic whipworm eggs in his intestines (Trichuris trichiura).
- The Iceman is the oldest known human to have been infected by the bacterium that causes Lyme disease; Helicobacter pylori aDNA and the genetic signature of Borrelia burgdorferi were detected in his DNA. As a result, one of the coldest cases in human history was thoroughly investigated thanks in large part to the science of paleomicrobiology.
What is Fossil stromatolite & Cyanobacteria ?
- Stromatolites are strange fossils whose biological origins weren't fully understood until a recent period of time. Stromatolites are layered colonial formations that are mostly generated by cyanobacteria, according to the majority of scientists today.
- The Stromatolites' surface layer is where the bacteria are active, and the underlying build-up is a lithified residue of previous microbial surface communities that might be considered a trace fossil. A single 1m building may be 2,000–3,000 years old because of how slowly these deposits accumulated.
- The phylum of gram-negative bacteria known as cyanobacteria, commonly referred to as cyanophyta, produces energy through photosynthesis. Although they are typically not formally categorized as algae, the word "cyanobacteria" relates to their hue, which also serves as the basis for the colloquial moniker "blue-green algae."
