I’m sure someone will know what these are. The halves are heavier than they look and fit together to form an imperfect sphere. The whole thing looks like a petrified walnut as the two halves fit together. The smaller globe is stuck inside the larger “shell”. The objects appear to be sandstone of some type (sandstone is abundant at Pearl Creek Farm) and I’m pretty sure they’re natural but not biological in nature. They were found near the creek and we find them or something similar occasionally, sometimes not broken apart. Any guesses?
