What does a Nautiloid look like?

In life, they are visible as a series of narrow wavy lines on the outer surface of the shell. Like their underlying septa, the sutures of the nautiloids are simple in shape, being either straight or slightly curved.

What did nautiloids eat?

The straight shelled nautiloids often eat jawless fish, trilobites and eurypterids for food. Once the gamma ray burst hits, they struggle to survive. Even when they try to go down into the depths of the ocean to escape the disaster, their shells shattered from the intense pressures of the deep.

Are nautiloids extinct?

They suffered large extinctions at the end of the Triassic Period (205 million years ago), and again at the end of the Miocene Epoch (5 million years ago). Today, only six species of nautiloids remain, the chambered or pearly nautiluses.

What are Mind Flayer ships called?

The Nautiloid
The Nautiloid is the standard ship of the line of the various illithid nations, and reflects the nature of the race. Its coiled shell provides the comfort of enclosed spaces while protecting the mind flayers from the irritating rays of the sun.

Are nautiloids good index fossils?

relation to ammonoids Ammonoids are important index fossils because of their wide geographic distribution in shallow marine waters, rapid evolution, and easily recognizable features.

How big is the biggest ammonite?

The largest known species of ammonite is Parapuzosia seppenradensis from the Late Cretaceous. The largest specimen found is 1.8 metres in diameter but is also incomplete. If it were complete, this ammonite’s total diameter could have been from 2.5-3.5 metres.

How big is a Spelljammer?

The size of spelljammers was typically measured as their “tonnage”, which reflected the volume occupied by a ship in spatial tons and was different from the typical tonnage of seafaring ships. One spatial ton was equivalent to a volume of 100 cubic yards (76 cubic meters).

How fast is a Nautiloid?

Movement: Magical Propulsion Unit Speed (magical) flying speed 45 ft.

What lives inside a nautilus shell?

The chambered or pearly nautilus is a cephalopod (a type of mollusk)—a distant cousin to squids, octopi, and cuttlefish. Unlike its color-changing cousins, though, the soft-bodied nautilus lives inside its hard external shell. The shell itself has many closed interior chambers or “compartments.”

How do ammonites and nautiloids differ?

A primary difference between ammonites and nautiloids is the siphuncle of ammonites (excepting Clymeniina) runs along the ventral periphery of the septa and camerae (i.e., the inner surface of the outer axis of the shell), while the siphuncle of nautiloids runs more or less through the center of the septa and camerae.

Why are there no dinosaurs in Indiana?

Massive glaciers came into the state and scraped, gouged and eroded layers upon layers of rock. The grinding action of these glaciers removed the evidence of entire geologic periods in Indiana. So the bad news—no dinosaurs in Indiana. We don’t even have Mesozoic rocks in the state.

What dinosaurs were found in Indiana?

No dinosaur bones have ever been found in Indiana. At the end of the Mesozoic, 65 mya, there was another mass extinction, wiping out many species, including the dinosaurs.
