Goniatitina
Goniatitina is a group of extinct cePhalopod mollusks that lived during the Paleozoic and Early Mesozoic eras. They were characterized by their internal shell, which was divided into several chambers. The Goniatitina lineage is believed to have originated from the ancestral group of Ammonoidea, to which modern squid and cuttlefish belong.
These marine animals were characterized by their spiral shells, which were typically divided into several whorls.
Fossil evidence indicates that Goniatitina species were quite large, with some reports suggesting mature specimens reached
