Journal: Doklady Earth Sciences
Year: 2020

The complex of modern physical methods for studying authigenic carbonate crusts in the Miocene bryozoan bioherms of the Kazantip Cape (Kerch Peninsula) has made it possible to reveal fossil biofilms and glycocalyx for the first time. These finds indicate that methanotrophic carbonate-precipitated bacteria during their activity strengthened brittle bryozoan skeletons. The presence of cavities in bioherms incrusted with goethite crusts, the presence of bitumen, pyrite, strontianite, barite, kutnag
