The species was named by young lawyer from Ottawa, Canada named Elkanah Billings. He would later be Canada's first official paleontologist. In his 1859 publication, On the Crinoideae of the Lower Silurian Rocks of Canada, Billings wrote, "The species is dedicated to Dr. E. Vancortlandt, of the city of Ottawa, whose zeal in the advancement of science has been productive of many beneficial results," The Ottawa Citizen newspaper wrote in a 2020 article about the Victorian era curio collector Dr. Edward Van Cortlandt who collected holotype fossil of this species.
The crinoid fossil genus and species was named by Samuel Addison Casseday (1831-1860), a Louisville area paleontologist.
These crinoid fossils were once part of the collection of southern Indiana paleontologist George K. Greene (1835-1917). It appeared that all of Greene's fossil collection was sold to American Museum of Natural History in New York City after his death but as it turns out there was one cabinet remained with the family and was past down to his descendants.
The fossil collection is now on display at the Falls of the Ohio State Park Interpretive Center till September 2024 after that it will be transferred to the Indiana State Museum. George Greene's great-great-grandson William "Bill" Bishop passed away on November 29, 2023 and his wish that fossils be donated.

A few weekends ago, we stopped at a Huck's Market (675 Western Kentucky Parkway, Beaver Dam, Kentucky) at on our way to a wedding in western Kentucky. While out stretching my legs, I examined a few boulders near the gas station/rest stop and found some fossils. The boulder located in the grass next to the parking lot near fuel pumps contained mostly crinoid stem and some brachiopods fossils. I am guessing they date to the Mississippian Period.
