• The first case of documented neoplasia in a non-hadrosaur dinosaur.
• Two different types of neoplasia in a single vertebra of a titanosaurid dinosaur from Upper Cretaceous of Brazil.
• This is the first histologically verified diagnosis of an osteoma in the dinosaur record.
Tumors are thought rare in dinosaurs, previously limited in distribution to a single family – hadrosaurs. Here we recognized two different neoplastic lesions, osteoma and hemangioma, in a single caudal vertebra of a titanosaur dinosaur from the Upper Cretaceous of Brazil, diagnosed on the basis of macroscopic, radiological and histological analysis. This is the first occurrence of neoplasia in a non-hadrosaur dinosaur. Therefore, neoplasia is not restricted to hadrosaur dinosaurs, as previously suggested.
