Yes, now that you mentioned, I think I see some berries on the top of the rock and on closer look it could be a layered rock also, ... (hope we get a closer look).

here it is again for the record:

What got my attention were some of the cilidrincal features that this rock at the center bottom of the image displays. One possibility for such kind of formations would be that we are seeing a chunk of stalactite (even wilder speculation than fossils!!!)...you know.... there have been some talks about caves and sinkholes .... I am sure that there should be some alternative explanations for that kind of formation.
