Weirdly this is about the fifth time I've read this in the last couple of months and it's out-of-date.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.

The rare double gotcha fact

I’m imagining a cabal of dinosaurs experts cackling and laughing “time to bring the bronto back, too many people are getting uppity!”

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!
