It is currently unclear whether sea scorpions traversed the waters with the changing seasons or only crossed once.Since their trail appears to end around 393 million years ago, scientists suspect they perished due to changes in their environment.
"We conclude that these new records evidence the diversity of larger arthropods in Australian deposits and that ongoing documentation of these rare fossils is required to further understand the Paleozoic ofPre-Cambrian Era Archean Eon : Formation of early continental crust; emergence of the first simple life forms .
