Abstract Extensive study of modern Bahamian stromatolites has resulted in a
comprehensive model for their formation. Modern Bahamian thrombolites—microbial
deposits with a mottled, clotted fabric—have not, however, received the same degree of
study. Current models link the Bahamian thrombolites with the presence of a mixed-bacterial-
and-metaphyte benthic ecosystem, whereas stromatolite formation is linked with an almost
exclusively bacterial benthic ecosystem. By focusing on the preserved fabrics of several ...
