weitnabelig evolute Explanation: weitnabelig heißt, dass die Windungen die jeweils vorher gegangene wenig umfassen. https://westfalen.museum-digital.de/index.php?t=objekt&oges=... Merkmale Goniatiten besitzen wie Ammoniten ein zumeist in einer Ebene spiralig eingewickeltes, gekammertes Gehäuse, das aus drei Schichten aufgebaut ist. Die Formen der Gehäuse variieren erheblich, von kugeligen bis zu dünnen scheibenförmigen Gehäusen. Die äußeren Windungen umfassen die jeweils inneren. Je nach dem Grad der Umfassung sind die Windungen involut – die inneren Windungen werden durch die äußeren mehr oder weniger verdeckt – oder evolut (die äußeren Windungen umfassen die inneren kaum). https://www.biologie-seite.de/Biologie/Goniatiten Coiled shells Many nautiloid and ammonoid shells are tightly coiled and grow about an axis in a single disk-like plane (they are therefore planispiral, a term that is also applied to the shells of some gastropods). In some species, younger whorls do not overlap earlier whorls; these shells are called evolute. In other species, the younger chambers partially cover earlier whorls; these shells are called convolute. Finally, some species have shells that are involute: the youngest whorls completely (or almost completely) cover all of the earlier whorls (as observed in the shell of Nautilus). https://www.digitalatlasofancientlife.org/learn/mollusca/cep... |
