Explanation:

Bone fossils often have pores due to their biological origin. They also typically have spongy layers surrounded by dense layers, characteristic of bone structure. Rocks may contain individual grains, be homogeneous throughout, or stick to the tongue (e.g., some clay - rich rocks), but these are not features that distinguish them from bone fossils.
