In his book A monograph of the trilobites of North America: with coloured models of the species, he mentions an abundance of “Calymene bufo” in similar conditions to that of the Windom.

[2] Later on in 1935, David M. Delo’s “Revision of the Phacopid trilobites” would name the genus Greenops in honor of Jacob Green’s work.

The American paleontologist James Hall, would be very influential in early scientific examination of the Hamilton group.

American geologist and malacologist, Timothy Abbott Conrad would describe many species found in the shale today.

The work of Hall, Vanuxem, Conrad and other geologists of the time would give the foundation of the study of the geologic context behind the Windom.

[4] Paleobiologist Gustav Arthur Cooper’s 1929 dissertation, “The Stratigraphy of the Hamilton Group of New York” was another very influential work to the study of the Windom shale.

When the Town of Hamburg purchased the abandoned quarry with the intention of turning it into a waste dump, lobbying efforts stepped in.

The lobbying efforts merged to become the Hamburg Natural History Society, Inc., and successfully purchased the site in 1993 for its preservation.
