Spinosaurus was thought to have lived from 106 to 93.6 Million years ago.
This was in the Albian Age(112 - 99.6Ma) and Cenomanian Age(99.6 - 93.6Ma) of the Cretaceous Period(145.5 - 65.5Ma).
They spanned the end of the Lower Cretaceous Epoch(145.5 - 99.6Ma) and the start of the Upper Cretaceous Epoch(99.6 - 65.5Ma). This was in the Mesozoic Era(251 - 65.5Ma) which was part of the Phanerozoic Eon(542Ma - Now).

They almost died out at the end of the Permian Period (251 million years ago), and again at the end of the Triassic Period (205 million years ago). They finally became extinct at the end of the Cretaceous Period (65 million years ago), perhaps as a result of a lowering of ocean levels.
