As a result, they have been used as biostratigraphic indicators in a variety of paleontological digs. However, the phylogenetic picture has been complicated by the discovery in Asia of both ancestral and derived carpolestids in the same stratigraphic layer.
As a consequence, these organisms have been employed as biostratigraphic indicators in various fossil digs. However, the evolutionary history has become more intricate due to the finding in Asia of both ancestral and derived carpolestids in the same geological stratum.
