Abstract
Partial remains of a titanosaur sauropod collected in the Tolar Formation (Upper Cretaceous) at the Atacama Desert (Antofagasta Region), northern Chile, is described, and a new species, Atacamatitan chilensis gen. et sp. nov., is erected. The material consists mainly of dorsal and caudal vertebrae, part of a humerus and a femur. The presence of a titanosaur confirms the Cretaceous age for the outcrops of red sandstone of the Tolar Formation whose age was previously uncertain, ranging from the Upper Cretaceous to the Paleocene. The new specimen represents the most complete dinosaur reported for this region and one of the most complete titanosaur known from Chile and the pacific margin of South America so far.
Um esqueleto incompleto de um dinossauro titanossaurídeo de depósitos da Formação Tolar (Cretáceo Superior) do deserto do Atacama (região de Antofagasta), norte do Chile é descrito e uma nova espécie, Atacamatitan chilensis gen. et sp. nov., é proposta. O material consiste principalmente de vértebras dorsais e caudais e de partes do úmero e fêmur. A presença de umtitanossauro confirma a idade Cretácea para os afloramentos de arenito avermelhado da Formação Tolar, que eram anteriormente tidos como depositados entre o Cretáceo Superior e o Paleoceno. O exemplar representa o mais completo titanossauro até hoje encontrado na região e um dos mais completos reportados até o momento do Chile e da margem do Oceano Pacífico na América do Sul.
