I am very, very curious myself. It doesn't look like a normal break pattern for a rock, and it looks too jagged (organic?) to be something ejected from the lander, so it is anomalous.

I've often thought that the whole site looked like that scene in Star Wars Ep IV where the 'droids are walking past a long huge skeleton on a Tatooine dune.

Maybe it's a tailbone? (harhar!)
