Nautiloids are first known from the late Cambrian Fengshan Formation of northeastern China, where they seem to have been quite diverse (at the time this was a warm shallow sea rich in marine life). However, although four orders have been proposed from the 131 species named, there is no certainty that all of these are valid, and indeed it is ...
Nautilus (from Latin nautilus 'paper nautilus', from Ancient Greek ναυτίλος nautílos 'little sailor') [3] are the ancient pelagic marine mollusc species of the cephalopod family Nautilidae. This is the sole extant family of the superfamily Nautilaceae and the suborder Nautilina .
The current classification of the Nautilida, in prevalent use, [1] is that of Bernhard Kummel (Kummel 1964) in the Treatise which divides the Nautilida into five superfamilies, the Aipocerataceae, Clydonautilaceae, Tainocerataceae, and Trigonocerataceae, mostly of the Paleozoic, and the later Nautilaceae.
Nautilus are unable to easily move across areas deeper than 800 metres, and most of their activity occurs at a depth of 100–300 metres deep. [4] Nautilus can occasionally be found closer to the surface than 100 metres, however, the minimum depth they can reach is determined by factors such as water temperature and season. [4]
The earliest cephalopods, [b] like Nautilus and some coeloids, appeared to be able to propel themselves forwards by directing their jet backwards. [ 42 ] : 289 Because they had an external shell, they would not have been able to generate their jets by contracting their mantle, so must have used alternate methods, such as by contracting their ...
The Ship Sarcophagus: a Phoenician ship carved on a sarcophagus, 2nd century AD.. The theory of Phoenician discovery of the Americas suggests that the earliest Old World contact with the Americas was not with Columbus or Norse settlers, but with the Phoenicians (or, alternatively, other Semitic peoples) in the first millennium BC.
100–1000: Weeden Island culture flourishes in coastal Florida. They are known for their extraordinarily well-preserved wood carvings. 200: The Adena culture of the Ohio River valley evolves into the Hopewellian exchange. 200–800: Late Eastern Woodlands cultures flourish in the Eastern North America.
