Udelartitan celeste Soto et al., 2024 (new genus and species)
(Type tail vertebrae of Udelartitan celeste, from Soto et al., 2024)
Meaning of name: Udelartitan = UdelaR [acronym for the Universidad de la República] titan [in Greek]; celeste = sky blue [in Spanish, referring to the nickname of Uruguayan teams in international sport competitions]
Age: Late Cretaceous (exact age uncertain)
Where found: Guichón Formation, Paysandú, Uruguay
How much is known: Multiple tail vertebrae and some limb bones. It is unknown how many of these bones belonged to the same individuals.
Notes: Udelartitan was a titanosaurian sauropod and one of the few Mesozoic dinosaurs known from Uruguay. Most known specimens of Udelartitan had been briefly described in 2012, but were left unnamed at the time. It may have been closely related to Alamosaurus from the southwestern United States, Baurutitan from Brazil, and Pellegrinisaurus from Argentina, with which it shares the feature of having a frontmost tail vertebra that is convex on both ends.

when somebody brings up cannibalism/human sacrifice in mesoamerican civilizations as a negative point to prove that ‘mesoamerica was barbaric and cruel’ i like to bring up the fact that europeans crushed and ate mummies as medicine back in the day
