This past July I was up collecting at Hungry Hollow near Arkona, Canada and ran into a couple of fellow fossil collectors. We chatted for a bit and one of them gave me the fossil below, a Nucleocrinus elegans.
Oral surface (top)
Basal surface (where the stem attached)
I think he felt bad for me as I complained that I hadn't found many blastoids at the site (despite their relative local abundance). I gave him some pieces of North Evans Limestone that are loaded with micro fossil fish and conodont teeth as a thank you. Sadly I didn't write their names down or I could give proper credit.
This is my third blastoid species from the Hungry Hollow member of the Widder formation (Devonian, Givetian stage) after Hyperoblastus reimanni and Heteroschisma canadensis.
