If you end up staring at the walls at some airport on your way home from your holiday gathering this year, consider using some of that down time to really stare at those walls.

As David Williams discovered while hanging around Seattle-Tacoma International Airport (SEA) recently, there are some cool-looking fossils in the limestone used to build the wall of the food court in Concourse A.   He says eagle-eyed travelers will probably find fossils in other parts of the airport – and in other airports – as well.

Williams in the author of the soon-to-be-published Stories in Stone: Travels through Urban Geology and writes more about these fossils on his blog.
