Maybe NASA will get a close-up of a ‘berry on a stick’. They are probably just erosional pedestals, but we don’t know that for certain.

Notice the sphere here are the same size as those back in eagle.

They seem to have a size limit that I can not explain. They all seem to reach a certain size. Tektites would vary in size, and the larger they got the less spherical they would become. Concretions would also very in size and they would be layered.

Mollusks Fossils, here on earth, have size limits. I have found layers in limestone where all the shell fossils are similar sizes. I am not saying the sphere on Mars are fossils, but so far, that is the only way I can explain their similar sizes and their size limit.

What throws me away from them being fossils is that they are evenly distributed throughout the parent rock and are not restricted to certain layers. When I find shell fossils, they are usually in layers.
