Im knocking this out now. Their bodies are made of chakra. Anything involving the Juubi absorbing the tailed beast, it takes their entire bodies, unlike when the juubi/shinju absorbed chakra from ninja in the joint army, their bodies stayed. So regardless of the physical forms their bodies take, their physical forms base element is chakra, and if given enough time, everything organic breaks down into its base element.

Like I said before, when they die, they disperse(as stated in the manga) like a shadow clone. But if they don't die, they heal/regenerate. But stuff gets iffy here because Gyuuki's cut off horn did not disperse, so it was either sealed with Gyuki a bit after or it was left to disperse, because it would have been a liability to allow a portion of its chakra to be left unattended. the Tentacle clone was different in that it was given more chakra to maintain the jutsu.

Gyuki's horns and the tooth that he lost in the 4th World War grew back by Boruto the movie. The 2 horns in the back grew back completely, but the ones in the front didn't. Maybe he likes it that way.

Conclusion: Tailed Beast dead body will break down into chakra either upon death or shortly after. Severed limbs may have a delay before breakdown. Their injuries heal/regenerate like a normal organic creature (but presumably faster).
