The Ordovician and Silurian benthic graptolite Ptilograptus Hall, 1865 (Graptolithina, Dendroidea)

The genus Ptilograptus is re-described from its type species and a revision of the included taxa is attempted. The genus is widely distributed from the Darriwilian (Middle Ordovician) to the Ludlow (Ludfordian) or even the Přídolí (upper Silurian), but its origin is uncertain and may be much earlier...
