Most mainstream paleontologists and geologists place dinosaurs on earth’s timeline at around 220 million and 65 million years ago, during the Mesozoic Era. Homo sapiens on the other hand, do not appear in the record until about 200,000 years ago - in the Middle Pleistocene, Middle Paleolithic (Eurasia), or Middle Stone Age (Africa).

Prokaryotes constitute the majority of sedimentary biomass, where they cycle organic carbon and regulate organic matter transformation. The microbes inhabiting sediment are diverse, and the factors controlling microbial community composition are not fully understood. Here, we characterized the prokaryotic community using 16S rRNA gene sequencing in 24 stratigraphic layers within a 89 cm (dated to ~1900 years old) sediment core from an anchialine sinkhole in the Bahamas with a stratified water column and anoxic bottom water. The microbial community was dominated by members of the Alphaproteobac...
