The results of the study of calcite microspherulites in carbonate breccia formed at the junction of biohermal and bioclastic limestones (Lower Maeotian, Cape Kazantip, Kerch Peninsula), the nature of which is still being discussed, are presented. The following analytical methods were used: chemical carbonate, gas chromatography, Raman spectroscopy, electron microscopy with EDS, isotope. The studies resulted in the following: the presence in the fossilized biofilms of the pelitomorphic matrix and
