Titanosaur found in Argentina may be oldest yet, says researcher
Ninjatitan zapatai lived approximately 140 million years ago (Early Cretaceous epoch) in what is now Patagonia, Argentina.
“During evolutionary history, sauropods had different moments, different pulses of gigantism, which were not only related to the group of titanosaurs,” said Dr. Pablo Ariel Gallina, a paleontologist at the Fundación Azara in Maimonides University and CONICET.
“The main importance of this fossil, apart from being a new species of titanosaur, is that it is the oldest recorded for this group worldwide,” a statement quoted researcher Pablo Gallina of the Conicet scientific council as saying.
“The presence of a basal titanosaurian sauropod in the lowermost Cretaceous of Patagonia supports the hypothesis that the group was established in the southern hemisphere and reinforces the idea of a Gondwanan origin for Titanosauria,” the researchers said.
