Scientists Discover the Largest and Last Dinosaur Species from the Sauropoda Family

The researchers have identified a newly discovered sauropod species, which is the largest of its kind and one of the last living members of its family.

"The first paleontologist discovered fossils of this species, which is now named Sidersaura marae, in 2012 in the Huincul Formation in Neuquén Province, Argentina."

New Sauropods Alongside Giant Meat-Eating Dinosaurs.

According to the journal Historical Biology, researchers required several excavations over a number of years to retrieve parts of giant dinosaurs, which originated from four individuals. These newly discovered animals likely died in a muddy area near a river, and although scavengers and water washed away some of their bones, many survived. The researchers found one new sauropod lying next to a giant carnivorous dinosaur named Meraxes gigas, which was revealed in 2022, while the other three were located 65 feet (20 meters) away.

The fossil of S. marae is approximately 93 to 96 million years old and originates from the early stage of the late Cretaceous period (100.5 million to 66 million years ago), representing the last chirps of dinosaurs before the catastrophic asteroid impact that wiped out non-avian dinosaurs.

The newly discovered sauropod measures up to 65 feet long and weighs 16.5 tons (15 metric tons). S. marae is a rebbachisaurid sauropod that typically weighs up to 10 tons (9 metric tons), raising questions about how this animal could grow to such a large size.

“This discovery opens up opportunities for new investigations and research to study how these animals can reach such sizes,”
the main author of the study, Lucas Nicolás Lerzo, a doctoral student at Maimónides University in Argentina.

"Rebbachisaurid is a family of sauropods with duck-like faces that feed on vegetation near the ground. Lerzo began studying the bones in 2017 and discovered that many features distinguish it from other rebbachisaurids."

Some of these differences are related to the size of the new species, which is very large. For example, the hind legs of S. marae are much stronger compared to its relatives, possibly to support more weight. The researchers named S. marae based on the unusual shape of its haemal arch, which is a bony structure in the tail. Sidersaura combines "sider," the Latin word for star, with the Greek word "saura," which means "lizard" or "reptile."
