Brachiosaurus I think. Brontosaurus was originally thought to be a separate species from Apatosaurus but later revealed to be the same.

Weirdly this is about the fifth time I've read this in the last couple of months and it's out-of-date. Brontosaurus and Apatosaurus are divorced and living as separate species again.

But this alienated Pluto so much that it refuses to be a planet and is out hiding in the Oort cloud again.

I think you mean the Kuiper belt, which is about 30 to 50 AU from the Sun and is where Pluto orbits.

The Oort cloud is between 2000 to 100,000 AU. A fair bit further away!
