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 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 ...
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]
Because of their oceanic habitat, studies of their life cycle have primarily been based on captive animals and their eggs have never been seen in the wild. [7] Although nautilus have been kept at public aquariums since the 1950s, the chambered nautilus was first bred in captivity at the Waikiki Aquarium in 1995 (a couple of other nautilus species had been bred earlier) and captive breeding ...

The first "national" collection for Irish antiquities was the British Museum in London, where many finds from before and after it was established in 1753 have ended up. However, from the foundation of the Dublin Royal Irish Academy in 1785 there was a local rival, which became the main destination of objects that were newly-found, or appeared ...
A shell midden at Enterprise, Florida in 1875.. The foundation of Florida was located in the continent of Gondwana at the South Pole 650 million years ago (Mya). When Gondwana collided with the continent of Laurentia 300 Mya, it had moved further north. 200 Mya, the merged continents containing what would be Florida, had moved north of the equator.
