Firstly you must know that a conglomerate is a sedimentary rock.
Only a sedimentary rock could have shells in it, and only limestone. Other rocks contain fossils like shells but only limestone can form them as the impression is filled by calcite, which collectively forms limestone.
It is a metamorphic rock formed from a progenitor sedimentary rock called a "conglomerate".
A conglomerate rock is a heterogeneous material.
Conglomerate is a clastic sedimentary rock.

No. Conglomerate is a clastic sedimentary rock.
No, metaconglomerate is a metamorphic rock, hence the "meta-" addition in front of the usually sedimentary rock conglomerate.
Sedimentary and conglomerate, as igneous and metamorphic are both formed underground where there is a high pressure and temperature.
