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).

What period of time did ammonites live in?
Devonian to cretaceous is the the geological age of ammonoids They first appeared during the Devonian Period (approximately 410 million years ago). 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.
How does the study of fossils represent the evolution of species over geological time?
The study of fossils represent the evolution of species by the time period between when they became fossils and what the ancestory line is
State the difference between geological evolution and organic evolution?
The word evolution has grown to be rather over-used and sometimes even misused, and is commonly used to refer to non-biological systems when talking about them in a sense of their changes over a period of time. For example, while computer systems do not evolve in the way biological organisms do, they have changed drastically over the years through a series of smaller changes. Outwardly this system appears very similar to biological evolution, and so evolution phraseology is useful in this context. Geologic evolution refers to a system of changes within a geological system. An example would be studying how a specific area has changed from ocean to mountains to desert over a period of time. Once again, geological systems do no progress in a "natural selection" sense such as true evolution, but they can change in drastic ways via a series of smaller changes over a very long period of time. Organic evolution presumably refers to a system of changes within a biological range. This could refer to the evolution of species or traits within a species, or may even relate to pre-biogenesis evolution of basic amino-acid strands.
What is the relationship between frequency and period?
Time period = 1 / frequency. Frequency = 1 / time period.

The first dinosaur fossil and the fossil on Vega island in 1986 were representatives of what geological time period?
The first dinosaur fossil ever found in Antarctica is called Antarctopelta. Its fossils date to the late Cretaceous period. Cryolophosaurus, the first theropod discovered in Antarctica, date back to the early Jurassic period.
What is geological scale?
The geological time scale organizes a long period of time.
How does the polar allosaurus have babies?
The "polar Allosaurus" is called Cryolophosaurus. Like all dinosaurs, Cryolophosaurus would have laid hard shelled eggs, and the babies would hatch after the eggs incubated for a period of time in the nest.
