	Michiganites ''Michiganites'' is a member of the ammonoid order Prolecanitida, named by Ruzhencev in 1962, which comes from the Meramacian stage of Mississippian Period (early Carboniferous The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carbonifero ... Visian). The shell of ''Michiganites'' is discoidal and smooth, as for the family. The ventral lobe of the suture is expanded; three lobes are formed on either side. ''Michiganites'' is placed in the suborder Prolecanitinae (the Prolecanitaceae of Hyatt 1884) and in the family Prolecanitidae along with related genera, ''Becanites'', ''Dombarocanites'', ''Eocanites'', ''Katacanites'', ''Metacanites'', and ''Prolecanites'' References * GONIAT on lin Paleobiology Database* Treatise on Invertebrate Paleontology, Part L, Ammonoidea; Geological Society of Ameri ...

picture info	Ammonoidea Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns.

	Prolecanitida Prolecanitida is an order of extinct ammonoidea, ammonoid cephalopods with discoidal to thinly lenticular shells with goniatitic or ceratitic sutures and which retained the simple retrochoanitic siphuncle with backward extending septal necks. As typical for ammonoids the siphuncle is along the ventral margin. Prolecanitids form a relatively small and stable order within the Ammonoidea with 43 named genera and about 1250 species, but with a long-ranging lineage of about 108 m.y. stretching from the Lower Carboniferous to the Triassic. Although not as diverse as their Goniatitida, goniatitid contemporaries, the Prolecanatida provided the stock from which all later Mesozoic ammonoids were derived. Evolution and phylogeny The origin of the Prolecanitida may be found in the Prolobitidae which was originally included in the Anarcestida but recently removed to the Goniatitida. Following their inception, the Prolecanitida divided into two lineages, identified by superfamilies; the earlier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Fossilworks Fossilworks is a portal which provides query, download, and analysis tools to facilitate access to the Paleobiology Database The Paleobiology Database is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms. History The Paleobiology Database (PBDB) originated in the NCEAS-funded Phanerozoic Marine Pale ..., a large relational database assembled by hundreds of paleontologists from around the world. History Fossilworks was created in 1998 by John Alroy and is housed at Macquarie University. It includes many analysis and data visualization tools formerly included in the Paleobiology Database.{{cite web, title=Frequently asked questions, url=http://www.fossilworks.org/cgi-bin/bridge.pl?page=FAQ, publisher=Fossilworks, access-date=17 December 2021 References {{Reflist External links {{Wikidata property, P842 * [Baidu]
