Sauropodas , a genus of osaurs , which is the largest animal species that has ever existed on Earth , stood out even among the osaur species with its physical features. It was known that these gigantic animals with various types of dollars such as Brontosaurus, Brachiosaurus and Diplodocus needed four thick and strong legs to carry their bodies .

In a study published in the International Journal of Plant and Animal Traces in 2019, it was suggested that these giant animals could have two legs , not four , and data supporting did not have four legs . had been reached. Recent studies by an American research team confirmed this research .

It was revealed that Sauropodas lived only on land

A fossil researcher named Roland T. Bird years ago, a fossil researcher named Bandera of Texas. He had detected unusual traces of the Oz in a field in the county. What made Researcher Bird’s determination unusual was that only traces of the osaurs belonged to the limbs manus (an animal’s forelimb). Roland T. Bird explained his observations in a letter published in 1940 as “These marks were undoubtedly the traces left by sauropods while swimming .

The evolution of paleontology (fossil science) has concluded that the Sauropods were terrestrial creatures, not aquatic creatures, as previously thought. Thus, the research of the fossil scientist Bird lost its validity . To explain the fact that only the forefoot prints remained, the alternative view was that the forelimbs of animals left a longer trace on a certain ground as they supported most of their body weight .

“There may only be species of zoosaurs that walk on their forelimbs”

Isaredollarser from the manus of the Sauropods was identified in 2007 in a limestone quarry called Coffee Hollow in the Glen Rose Formation, where many osaurus footprints are preserved from around 110 million years ago. These sauropoda traces in Texas have prompted researchers to reconsider the arguments put forward so far .

A group of researchers from Purdue University Fort Wayne and the Houston Museum of Natural Sciences studied three different traces of the Sauropoda manus alone. While the researchers could not definitively determine what kind of Sauropods left only manus traces, they emphasized that some osaur species walked only on manus . Stating that it is impossible to reach a clear decision about the idea that the isaredollarserine may be due to foot pressure or may have been left swimming, the researchers stated that future discoveries are needed to solve the issue .
