Phyllograptus is a genus of graptolites belonging to the order Graptoloidea, family Tetragraptidae.
Fossils of this genus have been found from the Early Ordovician (475–473 million years ago) in sediments in Australia, Bolivia, Canada, Chile, China, New Zealand, Norway, Spain, Sweden, the United Kingdom, and the United States. The typical length of a colony of these leaf-shaped animals could reach up to 3.5 centimeters. They were passively mobile planktonic suspension feeders. Phyllograptus species are excellent index fossils for identifying rocks from the Ordovician.
