Abstract
The Mesozoic paleo-ecological environment in Inner Mongolia is complex and diverse, providing a rich place for biological survival and evolution. In this paper, the systematics and taxonomic diversity of the Late Cretaceous squamates in Inner Mongolia were studied. The collected fossil specimens were subjected to CT scanning, three-dimensional reconstruction and morphological characteristics analysis to preliminarily identify the fossil taxa. The phylogenetic tree of the squamates was constructed by using the branch systematics method, and the phylogenetic relationship of the squamates was analyzed. The results show that the classification diversity of Late Cretaceous scaly in Inner Mongolia is high and widely distributed. This study provides new evidence for the in-depth understanding of the evolution and geographical distribution of scaly, and has important scientific significance for promoting the study of paleontology and geology. The results of this study provide a basis for the further development of related fields.
