Dinosaurs striding across the land bridge

The recent discovery of the most complete dinosaur skeleton ever found in Japan suggests the duck-billed creatures once stomped across the Bering Land Bridge. The dinosaur found in Japan is very similar to Edmontosaurus, fossils of which have been found throughout Alaska. The creatures may have been more adaptable and widespread than caribou are today.

Introducing ChemRex!

I neglected to mention one important development from yesterday. On landing night, after I had finished freaking out about our successful safe landing, I noticed that fellow ChemCam post-doc Nina Lanza was wearing a very special ChemCam shirt with this on the front: As a big fan of lasers and dinosaurs (my favorite toys as a kid were DinoRiders), I had to ask about it. Apparently Nina had made an …
