	Dictyonema (graptolite) ''Dictyonema'' is a genus of dendroid 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.

picture info	Graptolites Graptolites are a group of colonial animals, members of the subclass Graptolithina within the class Pterobranchia. These filter-feeding organisms are known chiefly from fossils found from the Middle Cambrian (Miaolingian, Wuliuan) through the Lower Carboniferous ( Mississippian). A possible early graptolite, ''Chaunograptus'', is known from the Middle Cambrian. Recent analyses have favored the idea that the living pterobranch ''Rhabdopleura'' represents an extant graptolite which diverged from the rest of the group in the Cambrian. Fossil graptolites and ''Rhabdopleura'' share a colony structure of interconnected zooids housed in organic tubes (theca) which have a basic structure of stacked half-rings (fuselli). Most extinct graptolites belong to two major orders: the bush-like sessile Dendroidea and the planktonic, free-floating Graptoloidea. These orders most likely evolved from encrusting pterobranchs similar to ''Rhabdopleura''. Due to their widespread abundance, plantkonic l ...

	Rhabdinopora ''Rhabdinopora'' is a genus of graptolites belonging to the family Anisograptidae. It is the earliest planktic Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucia ... graptolite and is presumably the ancestor of all later planktic graptoloids. Some species identified as the first planktid graptolite are: '' Rhabdinopora proparabola'' '' Rhabdinopora praeparabola'' '' Rhabdinopora parabola'' '' Rhabdinopora flabelliformis'' References Graptolite genera Ordovician animals of Asia Paleozoic life of Newfoundland and Labrador {{Paleo-deuterostome-stub ...
