Earlier, climate alterations had been reported from studies of tree rings and climate reconstructions. Reconstructions of historical dances and new compositions continue. This yields highly interpretable three dimensional reconstructions. The family Pteropodidae likely originated in Australasia based on biogeographic reconstructions. New studies using different methods continued to extend the period covered by reconstructions. Other archaeologists have criticized Corbo's reconstructions. Consequently, one halftone image has multiple plausible reconstructions. This led to methods for sparse 3-D reconstructions of scenes from multiple images. Some of the fragments are extensive enough to allow tentative reconstructions to be proposed. Research in projective 3-D reconstructions led to better understanding of camera calibration. Middle Chinese reconstructions by different modern linguists vary. There are also some fine, historically authentic reconstructions. These data have been used for alternative reconstructions. The ends are modern reconstructions replicating contemporary practice. The reconstructions of the Satavahana kings by historians fall into two categories.
