Sebayashi Formation
The Sebayashi Formation is a Barremian to Albian geologic formation in Japan.[1] Dinosaur remains are among the fossils that have been recovered from the formation, although only one species, Siamosaurus, has been referred to a specific genus.[2]

gollark: Well, do you know what a cryometaapion is?
gollark: [REDACTED] cryometaapions, mostly?

gollark: I might have to deploy GTech™ artistic engines™ against the problem of lemon image attainment.
gollark: Also, the monospace was quite cool. But this new background image is nicer.
