Gallery (stills and videos)
Here are a bunch of photos, and links to a few videos, of various Boxcavations we've done over the past several years.
This first set is a mallard that was buried for two years. That seems to have been a bit too long--many of the bones were soft and spongy after having been buried for that long (I do not know what the pH of the sand is).
Next is a (parts of) two harbor seals...the first shows a front right flipper that had been buried in horse manure. It ended up OK, but was stained fairly dark brown. The next two are from a single harbor seal, buried in sand.
Here are a couple shots of Steller sea lions. You can see a time-lapse video of the "field prepped" specimen here.
And, finally, some photos of Rakata. Rakata was a Sumatran tiger who lived at the zoo. He died of old age, and his skeleton is now at the Burke Museum in Seattle. Two short time-lapse videos can be seen here (front half, unfortunately not a very good sequence) and here (back half, which turned out really well).
