The authors originally classified Cal as a theropod, a member of a large group of bipedal, carnivorous dinosaurs that includes Tyrannosaurus, but several unpublished opinions beginning in 1995 suggested that the remains actually belonged to a sauropod (probably a titanosaur), a member of a very different group of quadrupedal, herbivorous dinosaurs with long necks and tails similar to Brachiosaurus. In 2006, the first published reference to Cal Ripken, Jr. as a sauropod appeared in a survey of Malagasy vertebrates by David Krause and colleagues.

abstract
| - The authors originally classified Cal as a theropod, a member of a large group of bipedal, carnivorous dinosaurs that includes Tyrannosaurus, but several unpublished opinions beginning in 1995 suggested that the remains actually belonged to a sauropod (probably a titanosaur), a member of a very different group of quadrupedal, herbivorous dinosaurs with long necks and tails similar to Brachiosaurus. In 2006, the first published reference to Cal Ripken, Jr. as a sauropod appeared in a survey of Malagasy vertebrates by David Krause and colleagues. Until the remains are properly described, the validity of any estimates will be questionable.
