A geode.
Moqui marbles are neat little concretions formed in sedimentary rock. Hematite cements the granules together into a hardened spherical mass, then erosion removes the surrounding sandstone.
Yes, geodes form in sedimentary rock. They also sometimes form in igneous rock. Use the link below to learn more.

No. A geode is not a shape; it is a kind of rock with a hollow interior filled with crystals. Earth's shape is an oblate spheroid.
A geode is a chemical sedimentary structure formed by mineral precipitation, similar to the way sedimentary cave structures are formed.
A geode is a chemical sedimentary structure formed by mineral precipitation, similar to the way sedimentary cave structures are formed.
A geode is basically a pocket or space or vug in an igneous or sedimentary rock structure that has partially filled or completely filled with minerals that have formed as a result of solutions entering the space. Because the mineralization mostly involves silicate deposition, the geode may be more erosion resistant that the rock that surrounds it. When the surrounding rock weathers and erodes, the geodes remain.
Geode is a rock or stone with crystals.

A hollow rock with crystals might be called a geode. A geode is a type of sedimentary rock that has crystals formed inside due to volcanic heating and cooling or by other chemicals seeping into the rock.
