Undescribed frontal appendages of Caryosyntrips sp.
Caryosyntrips ("nutcracker") is an extinct genus of radiodont which existed in Canada and the United States during the middle Cambrian. Caryosyntrips is known only from a handful of 14-segmented frontal appendages, which resemble nutcrackers, recovered from the Burgess Shale Formation. It was first named by Allison C. Daley, Graham E. Budd in 2010 and the type species is Caryosyntrips serratus.
The specimen showing here is probably the first Ordovician Caryosyntrips ever found globally.
