WebIn conclusion then the oldest well-proven hydrothermal vent fossil assemblage is Silurian (~430 Ma.) in age and comprises annelid tube worms, molluscs and brachiopods. All fossil vent communities contain ‘tube worms’ sensu lato, some of which belong to the Vestimentifera (part of the Siboglinidae). WebVarious microorganisms were observed coating the inner tube surfaces, together with 10–100 μm-sized Fe- and Zn-sulphide particles precipitated from vent fluids. The microbes and particulate sulphides become entombed within the tube wall as further layers of organic material are secreted by the worm, during tube-building episodes.
