Dichograptus (meaning two-branched writing or double-line marks) is an extinct genus of graptolites from the Ordovician.
[2] Dichograptus probably fed on plankton.
Individual animals were very tiny, only growing a few millimeters in length (1/8 of an inch).
Fossils of Dichograptus have been found in Argentina, Chile, China, Colombia (near Caño Cristales, Meta), New Zealand, Norway, and the United Kingdom.
