- Star Tales - Columba (ianridpath.com)
A constellation formed in the late 16th century by the Dutch cartographer and astronomer Petrus Plancius, who took some stars that Ptolemy in his Almagest had catalogued as lying outside Canis Major. These unformed stars can be seen, for example, on the southern half of Albrecht Dürer’s star chart of 1515 as two little groups, one group of six to the south of Lepus, from which the dove was formed, and another group of five between the hind legs of Canis Major which Plancius visualized as an olive branch.
- Late Triassic (Wikipedia)
The Late Triassic is the third and final epoch of the Triassic Period in the geologic time scale, spanning the time between 237 Ma and 201.4 Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian ages.
