The seismosaurus (セイスモサウルス, seisumosaurusu?) is a four-part fossil that can be donated to the museum. It was introduced in Wild World and also appears in City Folk. In New Leaf, the seismosaurus was renamed to diplodocus, which is made up of five individual fossils instead of four. However, the Japanese name remained the same until New Horizons.

Completing the Seismosaurus[]

In Wild World[]

Upon completion of the seismosaurus exhibit at the museum in Wild World, Blathers will give the player some information about the creature.

"The seismosaur is, quite simply, a stunning creature. Of the dinosaurs that we know about now, this is the absolute longest. Its body was rather small and quite light for its length, to be honest. Ah. Hoo. Terribly sorry. Who am I to judge its weight, eh wot?"

In City Folk[]

After donating all of the pieces of the seismosaurus to the museum in City Folk, Blathers will give the player information on the creature with the following dialogue.

"...Wait! Did the earth just move? Because the seismosaurus is complete! Hoo, what a mighty moment this is! The seismosaurus is the longest of all known dinosaurs, eh wot? Its body was small for its length, though, and rather light, as well... Proportionally, its brains were also rather light! HOO! I... beg your pardon! I was so enthralled, I... I spouted hot air like a boiling teapot, eh wot?"

In New Leaf[]

In New Leaf, a plaque by the display offers information about the fossil instead of Blathers.

"The diplodocus was an herbivore of the late Jurassic period sporting a tremendously long tail and neck. The neck was so long that, from snout to tail, its length could reach a staggering 175 feet long. Evidence suggests it would use its long, slender tail like a whip to defend itself from attackers."
