    Calcitization of aragonitic bryozoans in Cenozoic tropical carbonates from East Kalimantan, Indonesia

    Aragonite is commonly lost during the diagenesis of carbonate rocks, producing a significant bias in the fossil record. However, taphonomic loss of aragonitic biota can be nullified when skeletal aragonite is ...

    Three-Dimensional Morphological (CLSM) and Chemical (Raman) Imagery of Cellularly Mineralized Fossils

    Of all modes of fossilization, cellular mineralization, whether by the ­non-biologic process of permineralization (“petrifaction”) or by microbially ­mediated mineral precipitation (“authigenic mineralization”...

    Confocal Laser Scanning Microscopy and Raman (and Fluorescence) Spectroscopic Imagery of Permineralized Cambrian and Neoproterozoic Fossils

    Among all problems confronting the study of permineralized (petrified) ­fossils—the most life-like remnants preserved in the fossil record—two stand out, the need for (1) accurate documentation of their three-...
