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).
Distribution[]
Fossils of Dichograptus have been found in Argentina, Chile, China, Colombia (near Caño Cristales, Meta), New Zealand, Norway, and the United Kingdom.[3]
