Dictyonema (graptolite)
''Dictyonema'' is a genus of dendroid graptolithina, graptolites in the order Dendroidea. Fossil record Fossils of ''Dictyonema'' are found from the Upper Cambrian to the Devonian (age range: from 488.3 to 383.7 million years ago.). They are known from various localities in Europe, North America, South America, China and Morocco. Description These colonial organism are characterized by a conical, net-like structure. The colonies (known as rhabdosomes) are branched and may vary from almost discoidal to almost cylindrical. They were stationary planktonic suspension feeders.
