detritus
S is an unusual specimen because it is made up of three components (individually referred to S, X and JJ, clockwise from top) that became conjoined during the late stages of the calcification process. It is regarded as a single, though aggregate, object. What caused the merging of three distinctly separate structural entities is the preponderance of recent networking models: specifically, networks formed as separate informational pathways that inexorably converge into closed systems of content, reflected in the like-mindedness of individuals that gather around any particular node of informational mirroring. In its purest, perhaps reductive view, this object is a manifestation of the force that subsumes an individual into a collective identity. This is our most recent acquisition and is believed to have formed within the past four years (2016-2020).
