My science

Is there a word for a scientific fact that is accepted, only to be proven false some years later?
Pluto
Brontosaurus
and now Triceratops

I’m sure there are more of these, vagaries of science we learned as children ripped cruelly from our pathways in an effort to embarrass us in front of our children (well, your children, mine are imaginary). Let’s make a list? Hit me with an @reply if you know of something that should be on this list.

Update:
This post didn’t quite come out the way I wanted. The triceratops was only momentarily in danger as scientists decided to do away with the Torosaurus instead. Also, Jason wrote a post about a similar topic a couple months ago. Mesofacts are the name for facts that change slowly over time. It’s an important distinction, though, that these ‘facts’, Pluto and Brontosaurus, at least, were ripped away suddenly, instead of changing slowly over time. The only Twitter suggestion I thought fit completely was the loss of RBI as a telling baseball statistic.
