Abstract
Two new species of graptolite are described from the lower part of the Spirograptus turriculatus Biozone (lower Telychian) of Kallholn Quarry, Dalarna, Sweden. Pristiograptus paradoxus sp. nov. is ventrally curved and is more similar to uppermost Wenlock–Ludlow Bohemograptus species than to other Llandovery Pristiograptus species. Torquigraptus loveridgei sp. nov. is stratigraphically intermediate between the well-known species, T. planus and T. proteus.
