Thin sections of renalcid-group calcimicrobes;


Upper photo is VS;



Lower two photos are TS.



Note the structure is recrystallised but appears to be composed of composites of rounded objects, found in better preserved samples to be renalcid-group calcimicrobes.


Note sharp boundaries of microbial structure, either filled with micrite, or enclosing empty space (now filled with cement).
