Stratigraphy showing the layers (resin flows) preserved in the piece GRS-Ref-28627 and their contents in a very schematic manner with indication of the different significance, specific for our case of study, of the new terms eusyninclusions and parasyninclusions. The relative abundance in bioinclusions is represented at the right for each whole layer, except to for four layers in which there two indications, the relative quantity of bioinclusions in the top surface as striped points and the remained relative quantity of bioinclusions as a point at the middle of the layer; arrow indicates the interesting surface plenty of necrophagous dipterans, which is the top of the layer 12 containing the Oculudentavis naga holotype and a large portion of wings of a neuropteran individual. The large beetle most likely is an Elateroidea. The thicknesses of the layers represented are the greater observed, but they vary along the two apices of the piece and also as observed in their contacts with the two surfaces of the piece in sides A and B (these sides are illustrated in Fig. 4A—the side A- and Fig. 4C—the side B-); original thicknesses of layers 1 and 13 greater and represented as preserved. The taphonomy of the piece (mostly of the layers 12 and 13) stablished the chronology from the base (layer 1, the oldest) to the top (layer 13, the younger).
