A Possible Euhelopodid from the Jehol Biota, Liaoning of China

Our paper conducted a re-examine of the Sauropod individuals PMoL from the Jehol Biota, Lower Cretaceous, Liaoning of China, including partial vertebrae and appendicula. First, we re-exam the osteology of the PMoL. Next, we used TNT 1.5 and PAUP 4.0 software and the newest matrix of the Titanosauriformes to analyze the phylogenetic position of the PMoL, the result revealed that PMoL was reconsidered in the Euhelopodid. Then, the comparison in the PMoL and other Titanosauriformes in the Jehol Biota was conducted. Finally, we conducted a paleobiogeographic analysis to infer the origination of the Euhelopodidae and considered that the origin region of the Euhelopodidae is Asia.
