I'll take the opposite end and say it was discovered.

If you "discovered a dinosaur" that was completely mislabeled and of the oldest dinosaurs known to man "hiding in plain sight" - you deserve it.

Certainly it is a significant contribution, but I have to admit that my mental image when reading someone dicovered an ancient sword is of someone digging it out of the ground.

Well yes. From the article the digging out of the ground part likely happened but maybe a 100 years previously.

> Hey look, I just discovered a dinosaur at the natural history museum! It's older than they thought it was!

I mean, that actually happens, doesn't it? It's not that unusual for new species to be identified, misclassified in museums.

Uncovered? Refound?

I would like a better word, phrase for "sharing something that I just figured out, but didn't invent or create myself." Some thing like "News to me."

For instance, I'm currently "discovering" recipes for pumpkin pie. More of drunken sailor's walk thru an underspecified problem space.

It was discovered because no one really knew what it was before this.
