Summary of the taxonomic history of Late Triassic sauropodomorphs. The colour code corresponds to the decades in which the specimens used as holotypes for new genera were first collected, and, to the right, there is a list that indicates in which year a description of the specimen was first published, even if it was not a formal or detailed description. The taxa are grouped by regions, showing their alpha diversity. The time separating the discovery from the description does not mean that the specimen was not used as reference material in comparative anatomy. Although roughly half of the specimens used to erect the genera in this chart were discovered before or during the 1960s, only five genera were erected in the same interval. The infographic helps to illustrate that taxonomic revision of the material stored in collections around the world must be considered a constant work in progress.
