It’s time for Trilobite Tuesday! The construction of New York State’s Erie Canal from 1817 through 1825 unearthed a treasure trove of Silurian-age Rochester Shale fossils. At the time, these 420-million-year-old specimens caused much confusion and consternation among the scientific community. Quite simply, no one had ever previously seen material quite like this, and few knew what to make of these fossil riches. Some of the earliest scientific descriptions of many ancient species, including Arctinurus boltoni (pictured here), were based on discoveries made within this renowned locale in western New York. The site has long been famous for its outstanding preservation and abundance of invertebrate life, with more than 200 described species including corals, bryozoans, brachiopods, bivalves and more than a dozen recognized trilobite species. #trilobite #trilobites #fossil #fossils #amnh #insideamnh #eriecanal #rochesterny #rochesterny
