Donation to the museum[]

In New Horizons[]

Upon donation to the museum or selecting "Tell me more about this!", Blathers will say:

"The eusthenopteron is famous for being the link between fish and land animals long before dinosaurs. It seems to have had strong fins capable of pulling it around areas where the water was shallow. When most creatures lived in the sea...they dreamed of land. If not for them, we mightn't be here today! Imagine if we'd not left the oceans... How might fashion and music be different in an aquatic world? How would we resolve differences? Perhaps some sort of ink-squirting contest of champions?"

The eusthenopteron is displayed on the right side of the first fossil room, next to the dunkleosteus and myllokunmingia.

Main article: Eusthenopteron on Wikipedia

Eusthenopteron is a genus of prehistoric sarcopterygian (often called lobe-finned fishes) which has attained an iconic status from its close relationships to tetrapods. The name derives from two Greek stems—eustheno- "strength" and -pteron "wing" and thus "strongly developed fins". Early depictions of this animal show it emerging onto land; however, paleontologists now widely agree that it was a strictly aquatic animal. The genus Eusthenopteron is known from several species that lived during the Late Devonian period, about 385 million years ago. Eusthenopteron was first described by J. F. Whiteaves in 1881, as part of a large collection of fishes from Miguasha, Quebec. Some 2,000 Eusthenopteron specimens have been collected from Miguasha, one of which was the object of intensely detailed study and several papers from the 1940s to the 1990s by paleoichthyologist Erik Jarvik.


  • Blathers references Splatoon in his description of the fossil, but whether he's referencing the Splatfest events (where players choose a team based on their preference between two (in the first two games) or three (in the third) choices, then play Turf War matches against each other to help their team win) or just Turf War in general is uncertain.
