III Jornadas Internacionales sobre Paleontología de Dinosaurios y su Entorno Salas de los Infantes, Burgos An Overview of Titanosaur Evolution and Phylogeny Una revisión de la evolución y fi logenia de los Titanosaurios
Titanosaurus was named in 1877 for two caudal vertebrae and an isolated femur from Cretaceous rocks of central India. Titanosauridae was coined soon afterwards to encompass numerous taxa, despite their often tenuous associations and limited morphological overlap. Long recognized as wastebasket taxa,...
