This slab from the Jince Formation shows an association of the rare agnostid species Diplorrhina cuneifera and Onymagnostus hybridus. The Onymagnostus hybridus is approximately 9 mm long, while the Diplorrhina cuneifera measures around 7 mm. The latter species is particularly rare as articulated specimens. Diplorrhina cuneifera is sometimes still classified as Peronopsis cuneifera.
