Proterochampsa is a genus of extinct crocodile-like reptiles that lived during the Late Triassic period. The word proterochampsa is a combination of two Greek words, "protero" meaning early and "champsa" meaning crocodile. There are several synonyms for the word Proterochampsa such as Protosuchus, Procaimanoidea, Redondasaurus, Stagonolepis, and Zanclodon. The reason behind having synonyms for this genus is the discovery of fossils belonging to the same species but with different names. These synonyms can create confusion among researchers and hamper the study of these reptiles. However, with improved technology and research methods, it becomes easier to identify and classify these species accurately.
