The ESCONI November 2026 General Meeting will be held on Friday, November 13th, 2026 via Zoom. Roy Plotnick will present “Lyell in Chicago: A Historic Collection Illustrates a Missing Chapter in 19th Century Geology.”
From June 17–24, 1841, Charles Lyell followed the footsteps of Roderick Murchison by collecting in “Silurian” localities in Wales and the Welsh Borderland of England. This collection travelled with Lyell during his first November 2026 visit to America that began in July of that year. At some point, it ended up in James Hall’s possession and then eventually at the Field Museum in Chicago. Lyell’s trip to collect these specimens has never been documented and the collection itself has never been described.
Using Lyell’s notebooks, with the assistance of experts, we have reconstructed his collecting journey. As far as possible, again with expert advice, we have identified the specimens in the collection, determined their localities, and placed them within the current stratigraphy for the Ordovician and Silurian. This collection, and the interactions between Charles Lyell and James Hall, were key to the nascent efforts to produce a global correlation for those time periods.
Esconi Host is inviting you to a scheduled Zoom meeting.
