Encrinurus multisegmentatus, Lichas laxatus, Tetradium wrangeli, 
Atrypa imbricata, and Halysites parallelus are all typical species of the

the region.

Obolus conglomerate .15-.80 m. 
In Dalecarlia there is no Cambrian, the Obolus conglomerate resting 
on the granite. It contains Obolus apollinis and is followed by a thin 
bed of greenish gray glauconitic clay-shale which contains some 
fragments of Obolus. Above comes a thin bed of glauconitic limestone 
which contains Obolus fragments and Lycophoria laevis Stolley. 
This Wiman correlates with the Ceratopyge limestone on the basis 
of the latter fossil. 
At a single locality (Skattungbyn) Térnquist found in shales with 
interbedded slabs of limestone, Tetragraptus serra, T. quadribrachiatus, 
Dichograptus octobrachiatus, Phyllograptus densus, and three species 
of Didymograptus. The limestone contained Pliomera térnquisti 
Holm, Megalasmdes dalecarlica, Ampyx pater, and Agnostus térnquisti 
Holm. In general however, the Planilimbatakalk is present, followed 
by the Limbata limestone. Megalaspis planilimbata, M. limbata,
