It took him 7,000 hours over 5.5 years, during which he did little else. For that reason, the dinosaur carries his name—Borealopelta markmitchelli. (The first half comes from the Latin for “northern shield.”) So basically, prepari…

This was the most remarkable part about the whole thing as well. 7,000 hours just working on a single fossil. This man must have extraordinary patience

Still 30%-ish away from being an expert! On a serious note, compare that rhythm with our field...

Note: birds are technically dinosaurs http://tolweb.org/Dinosauria/14883

And dinosaurs are reptiles, mammals and reptiles are amniotes [1], both amniotes and amphibians are tetrapods, tetrapods are actually fish[2], and there's no such thing as a fish[3]!

So we have more in common with all land animals than a fish has with any other fish?

No, plenty of fish are closely related. There is however a lot more diversity so the extreme cases are far more extreme.

I wonder if they'll get a good image of the dinosaur's insides! What could they use to see through the rock?

Actually kudos to the mine workers and mine management for halting operations and letting archaeologists access the site.

The cost involved here is enormous with this, so such an operations often decide to ignore the bones instead.

I've read that we have more in common with fungi than plants.

I vaguely remebering reading (I think it was in The Selfish Gene) that we are more closely related to salmon than salmon are to sharks.

Is it that surprising? The land is populated only by the descendants of a few species that moved into it.
