Late Wenlock to Early Ludlow graptolites from Albania

Graptolites of the Late Homerian (Wenlock) Pristiograptus (?)ludensis Zone and the Early Gorstian (Ludlow) Neodiversograptus nilssoni Zone are described from the Muhuri Black Shale Formation of the Hurdh Muhuri area of northeastern Albania. The graptolites are strongly tectonized, but are identifiable to the species level. The material includes 14 species of monograptid and retiolitid graptolites from four samples.
