Time lapse photography of modern stromatolite formation in a laboratory setting gives some revealing clues regarding varied cumulative structures observed in nature. Due to intense UV (ultra violet) radiation during the day, the stromatolitic bacteria restrict their vigorous activity to night time. Fine grain sediments are bound together by excretions, adhered atop one another by the bacterias flagella, forming layers that correspond to periods of high activity. Thus, these sometimes elaborate structures are the means of providing shelter and protection from the harsh environment constructed by certain microscopic organisms, working somewhat in unison.
