Summary
| Description |
(public display, Cincinnati Museum of Natural History & Science, Cincinnati, Ohio, USA) Nautiloids are squids-in-shells. In the Paleozoic, many forms had a straight shell, but some had loosely coiled or tightly coiled shells. Nautiloids are still alive today, but only represented by a small number of species in modern oceans - all have tightly coiled shells. Seen here is Eutrephoceras, an extinct nautiloid with a tightly coiled shell. This genus existed from the Mesozoic to the Tertiary. Classification: Animalia, Mollusca, Cephalopoda, Nautiloidea, Nautilida, Nautilidae Stratigraphy: unrecorded / undisclosed Locality: unrecorded / undisclosed Info. at: <a href="https://en.wikipedia.org/wiki/Eutrephoceras" rel="noreferrer nofollow">en.wikipedia.org/wiki/Eutrephoceras</a> |
