Ammonites are very common fossils from the Jurassic Period. They were dominant in the ocean during and before the Jurassic Period.
During the Permian period 250 million years ago, all of the continents were massed together into one supercontinent, Pangaea. The Atlantic Ocean didn't form until Pangaea broke apart, with the Americas moving west and Africa and Europe moving east. That didn't begin until the late Jurassic, about 100 million years later.
It can be estimated that around 100 million years ago, after Pangea began drifting apart, the Atlantic Ocean was opened up.
