Uberabatitan ribeiroi
(Ribeiro's Uberaba Giant)Etymology
Uberabatitan is derived from "Uberaba" (the city where it was discovered) and the Greek "titan" (giant).
The
species epithet,
ribeiroi, honours Luiz Carlos Borges Ribeiro, director of the Centro de Pesquisas Paleontológicas Lewellyn Price, for his consistent support of palaeontological research in Minas Gerais State.
Discovery
The remains of
Uberabatitan were discovered at the "BR-050 B site" in the Serra da Galga Formation of the Bauru Group (previously known as the Serra da Galga Member of the Marília Formation), Uberaba city, Minas Gerais state, Brasil.
More than sixty bones from what were thought to be three seperate specimens, of different sizes and probably different ages, were found at this quarry, with an acronym added to the end of their catalogue numbers to identify the individuals: "specimen A" (the holotype) = UrHo, "specimen B" = UrB, and "specimen C = UrC).
In 2019, Silva
et al canned the acronyms, having realised they represented at least five different specimens and possibly more, and stripped the initial
holotype down from thirty-nine bones to the three (CPPLIP-912: a left shin, CPPLIP-1107: a left calfbone, and CPPLIP-1082: a left ankle) that represent the most complete likely articulated set of elements. The rest of the original holotype were relegated to referred specimens along with those that were initially listed as "specimen B" and "specimen C", plus six more specimens that were later found at the same locality.
