Phyllograptus

Phyllograptus is a graptolite genus of the order Graptoloidea, in the family Phyllograptidae.

Fossils of this genus have been found in the Early Ordovician (475-473 million years ago), in the sediments of Australia, Bolivia, Canada, Chile, China, New Zealand, Norway, Spain, Sweden, the United Kingdom and United States.

The normal length of a colony of these leaf-shaped animals could reach a length of 3.5 cm. They were passively mobile planktonic suspension feeders.

Phyllograptus species are excellent index fossils or guide fossils for identifying Ordovician rocks.
