nautiloids

There's no hint of a shell; previous theories had postulated a shelled common ancestor to squid, nautiloids, and ammonoids, but either this was a specialized branch that lost the shell, or modern cephalopod groups independently re-evolved the structure.

I also really like the scenery with the nautiloids.

What initially was a rudimentary echolocating ability to find hard-bodied nautiloids in surface waters 40 million years ago was perfected, as nautiloids declined, into a refined biosonar system able to find soft-bodied squid as they migrate downward during the day.

Since I'm doing links here are a pair of crackers from BoingBoing: knitted nautiloids and human hair lampshades.

But when we looked at nautiloids on Seven Cave Shelf and in Nautiloid Canyon, Gish pointed out that even if there was a tendency for the fossils to be oriented the way Austin says they are, they could be that way just because the current carried them there; there is no necessity for catastrophic burial nor evidence for a mass kill.

In the seas primitive sharks common and very diverse, echinoderms (especially crinoids and blastoids) abundant, Corals, bryozoa, and and brachiopods (Productida, Spriferida, etc) very common; Goniatites common, trilobites and nautiloids in decline.

Panelled in black marble and cherry wood, the marble is full of fossilised nautiloids.

She loved the odd-looking trees; the dragonflies; the cockroaches; the life below the ocean surface that she visited from time to time by diving; nautiloids, trilobites, sharks, fields of crinoids like fields of lilies, reefs built by animals that were not corals.

So Fle - ta's hooves avoided trampling the sponges and fernlike graptolites, and the squidlike nautiloids watched with - out reaction.
