It would take in water and force it out through its siphon at high speed thus propelling itself in the opposite direction, again like a modern cuttlefish or octopus. The specimen below was made up from a genuine tooth and partial root set together and any gaps filled with plaster.

The look nearly identical so unless you are one of the world's leading experts on fossil cephalopods, good luck telling them apart. It had a soft squid-like body inside a cone Climate change and EVs: How will future cars stem global warming? The surface is ornamented by a network of fine lirae (Sweet 1964:K224).

[1][4] Other large markets include Europe[1] (particularly Germany),[4] Australia[1] and Japan. When I first started out collecting the fossil shows set the benchmark not only for what was real or fake (yes many fakes are peddled at the shows) but also allow for the up-close evaluation necessary to discern those subtle differences that make one fossil A+ or another a failing grade. An orthoceras is an ancient mollusk that lived in the Ordovician period. Morocco is known for its argan trees, and the oil pressed from the nuts is prized for its culinary and cosmetic properties, but sometimes what is sold as pure argan is actually vegetable oil mixed with a little argan (to give it the right aroma), and some turmeric to give it more color. But if an orthoceras survived long enough, it could grow more than twice a persons height. Check out ourfossil sectionat Micheals Gems and Glass, whether it be in person or online.
