This story about a pipeline digger cracking through a fossilized dinosaur tail made me wonder: Does handling dinosaur bones make one Tamei?

Lizards are considered Sheratzim, but by and large Sheratzim are "creepy crawling things", so maybe only smaller dinosaurs, especially small, four-legged dinosaurs fit the description. Some claim that dinosaurs were part of an earlier creation that was later destroyed; if so, would small, Sheretz-like dinosaurs even count?

This would seem to depend on whether or not fossils are still bones al pi halacha. – yoel Oct 3 '13 at 17:02

I don't know how you know what species are sheratzim. – Double AA Oct 3 '13 at 17:29
@DoubleAA, I linked to a post that gave a general list. – Seth J Oct 3 '13 at 17:31

once an animal carcass has dried it is no longer tamei. see mishna 1 in keilim (bartenura)
