Figure 3: Example of an evolutionary timeline retrieved using PAReTT for the Lazuli bunting. The left panel indicates the major geologic timescale of the past 2000 million years including the prevailing Phanerozoic Eon as well as the subdivisions by era Paleozoic which lasted until approximately 250 MYA when the Mesozoic started which lasted until 65 MYA. As is illustrated, this period was marked by the emergence of the first birds in the class Aves approximately 110 MYA. The species currently recognized in the family Cardinalidae emerged in the Cenozoic era with most species of the genus Passerina first emerging 4 MYA.
