Biotic composition changed dramatically across the Cretaceous-Paleogene (K-PG) ca. 65 Ma and marks a real phenomenon, a response reflecting myriad complex factors associated with extinction and survivorship processes. In the southern high latitudes, the patterns of macroinvertebrates are proving distinct from the north, indicating that although the mechanisms driving the observed composition and biodiversity may be comparable, they have, in part, a unique suite of historical attributes. The early Danian Interval was characterized by opportunistic and migrant taxa that infilled the ecological vacuum left by the mass extinction in this 'brave new world'. But, what is the origin of many new groups recorded in the Danian?
