![]() Their fossil shells usually take the form of planispirals, although there were some helically spiralled and non-spiralled forms (known as "heteromorphs"). Ammonites' closest living relative is probably not the modern Nautilus (which they outwardly resemble), but rather the subclass Coleoidea (octopus, squid, and cuttlefish). The first ammonites appeared in the Devonian, and the Cretaceous–Paleogene extinction event wiped off the last species.Ammonites are a group of marine animals of the subclass Ammonoidea in the class Cephalopoda, phylum Mollusca. These mollusks, referred to as ammonites, are more closely linked to living coleoids (such as octopuses, squid, and cuttlefish) than shelled nautiloids like the living Nautilus species. The ammonite is displayed on the left side of the first fossil room, next to the trilobite and anomalocaris.Īmmonite in catalog in New Horizons Further informationĪ picture of Asteroceras, a Jurassic ammonite from England Main article: Ammonite on WikipediaĪmmonoids are a group of extinct marine mollusks belonging to the Ammonoidea subgroup of the Cephalopoda class. "Ammonites were creatures that lived before and all the way through the age of dinosaurs! Because different species lived at different times, their shells are sometimes used as "index fossils." In other words, these creatures act as markers in time, helping to identify the age of other formations! Who knows what other secrets lie hidden in those spiral shells?" When the player shows Blathers the ammonite in New Horizons, he will reply with the following dialogue: Oddly, the ammonite is a closer relative to the squid or octopus than to the chambered nautilus." In New Horizons ![]() However, theories speculate that giant varieties existed as well, with shells six feet in diameter. "Ammonites were sea creatures with shells ranging from a few inches to a few feet in diameter. In New Leaf, a plaque by the display offers information about the fossil instead of Blathers. I spouted hot air like a teapot, eh wot?" In New Leaf ![]() Hoo no! Actually, it's closer to the squid and octopus! Sadly, the only fossils we can find are mere shells, so we know not what sort of bodies they had. But it isn't a member of that family at all. "Hoo my, simply wonderful! A truly rare fossil! An ammonite, you see, is not what it seems, eh wot? At first glance, you'd think it was related to the conch. When the player shows Blathers the ammonite in City Folk, he will reply with the following dialogue: I went on rather long, didn't I? Forgive me!" In City Folk Despite extensive research, we're still not sure what their bodies looked like. But have I got a whopper of a surprise for you! They are actually part of the same family as squid and octopuses! Just imagine! All that remains of these enigmatic creatures are their shells. "Hoo! Indeed, WOO hoo! Amazing! This fossil is an almost flawless specimen! The ammonite looks like it would be related to spiral-shelled creatures. When the player presents the ammonite to Blathers at the museum in Wild World, he will reply with the following dialogue: Spewing out more information than necessary. Blathers, you ninny! I've gone and done it again. Time and tide wait for neither man nor beast, wot! Oh, hoo. ![]() Their extinction coincided with that of the dinosaurs. Fascinating, no? Ammonites existed from the Devonian period, some 400 million years ago, to the end of the Cretaceous period. The closest living relative to the ammonite is the chambered nautilus. Though ammonites lived in shells, they were not shellfish, but rather mollusks, like octopuses and squid. Now then, I know a thing or two about these creatures. This fossil is of exceedingly superior quality, wot wot. "Well! Hoo and hoo again! An ammonite! My stars! A very impressive find! Ah yes, wonderful. When the player presents the ammonite to Blathers at the museum in Animal Crossing, he will reply with the following dialogue: Donation to the museum In Animal Crossing
