Abstract

The Upper Jurassic – Lower Cretaceous limestones from Buila-Vânturariţa massif partly consisting of reef build-ups, are characterised by an important component of microbial organisms. This paper describes and illustrates some of the most important structures interpreted as having a microbial nature: “Tubiphytes” and Bacinella-type structures, cyanobacterial structures, micritic crusts, and peloidal structures. Most of these structures are related to different shallow-water environments, from intertidal, high-energy environment, to protected low energy subtidal environment.
