Many fossils from the past are found in completely different environments. This can be explained by tectonic plate movement or continental drift. The Earth is made up of tectonic plates that float on the semi-liquid magma below. The plates are moving very slowly, but over millions of years, made changes have occurred. Earth used to be a single humongous landmass, known as Pangaea. The fossils were most likely formed around Pangaea's time.

Pangaea was made up of different tectonic plates, and as they drifted away from each other, Pangaea broke up. Eventually, the plates settled in their present homes, although they still carried the remains of organisms from their home. The current Antarctic plate no doubt used to be in South Pangaea. The tectonic plates are still moving, however, and eventually Pangaea will reform on the opposite side of the Earth.
