Discovery and naming
The Udelartitan fossil material was discovered in 2006 within sediments of the
In 2024, Soto et al. described Udelartitan celeste as a new genus and species of titanosaur sauropod based on these fossil remains. The generic name, Udelartitan, combines "UdelaR", an acronym for the Universidad de la República (whose collection of vertebrae fossils includes those assigned to Udelartitan), with the word "titan", a common suffix for giant sauropod names, referencing the pre-Olympian gods of Greek mythology. The specific name, celeste, is a Spanish word for sky blue, referencing the nickname given to some Uruguayan athletic teams.[1]
Description
Based on other titanosaurs known from more complete skeletons, Soto et al. (2024) suggest that Udelartitan was about 15–16 metres (49–52 ft) in body length.[1]
Classification
In their preliminary description of some of the Udelartitan fossil material in 2012, Soto, Perea & Cambiaso used the general morphology of the caudal vertebrae and astragalus to suggest that it likely belonged to a
