	Nassellaria Nassellaria is an order of Rhizaria belonging to the class Radiolaria. The organisms of this order are characterized by a skeleton cross link with a cone or ring. Introduction Nassellaria is an order of Radiolaria under the class Polycystina. These organisms are unicellular eukaryotic heterotrophic plankton typically with a siliceous cone-shaped skeleton. The most common group of radiolarians are the polycystine radiolarians, which are divided into two subgroups: the spumellarians and the nassellarians. Both spumellarians and nassellarians are common chert-forming microfossils and are important in stratigraphical dating, as the oldest radiolarians are Precambrian in age. The nassellarians appear in the fossil record much later than their other polycystine relatives, the spumellarians. spumellarians can be seen as far back as the Precambrian, whereas nassellarians do not begin to appear until the Carboniferous. Nassellarians are believed to be have been increasing in species dive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Eukaryota Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the Three-domain system, three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard (archaea), Asgard archaea. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass (ecology), biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. The ...
