Which geological events occurred in New York State at approximately the same time that eurypterids first appeared?
Eurypterids first appeared during the Ordovician period, approximately 470 million years ago. During this time, New York State was primarily covered by shallow seas, experiencing significant marine transgressions and regressions. Geological events included the deposition of sedimentary rocks, such as limestone and shale, and the formation of the Taconic Orogeny, which marked the uplift of mountains due to tectonic activities. These processes contributed to the diverse marine environments where eurypterids thrived.
