context_page_description: Titanosaurus is a dubious genus of sauropod dinosaurs, first described by Lydekker in 1877. It is known from the Maastrichtian Lameta Formation of India.
context_section_description: As the type genus of Titanosauria, Titanosaurus at times became a wastebasket taxon for a number of titanosaurs, including those not just from India but also southern Europe, Laos, and South America. Only two among these, however, are currently considered species of Titanosaurus: T. indicus and T. blandfordi, both of which are considered nomina dubia.
  Other species formerly referred to this genus include: 
  "Titanosaurus" rahioliensis - Described based on teeth, this species is now considered an indeterminate neosauropod.
  "Titanosaurus" colberti - This species was the most well-known species of Titanosaurus, but has been moved into its own genus, Isisaurus.
  "Titanosaurus" australis - Known from relatively complete remains, but has been renamed Neuquensaurus.
  "Titanosaurus" nanus - A small species found to be non diagnostic, and hence a nomen dubium.
  "Titanosaurus" robustus - Now referred to Neuquensaurus.
  "Titanosaurus" madagascariensis - nomen dubium; UCB 92305 apparently related to Vahiny, while UCM 92829 has been reassigned to Rapetosaurus.
  "Titanosaurus" falloti - This large species, native to Laos, has disputed affinities. It has been considered synonymous with Tangvayosaurus and Huabeisaurus, but the remains are too fragmentary to be sure.
  "Titanosaurus" valdensis - Referred to a new genus, Iuticosaurus, but still considered a nomen dubium.
  "Titanosaurus" lydekkeri - Also referred to Iuticosaurus, but its relation to I. valdensis is uncertain.
  "Titanosaurus" dacus - A dwarf titanosaur; now moved to the genus Magyarosaurus.
