Mazon Creek Fossils

300 million years old

Mazon Creek fossils have been found on the banks of the River Mazon, also known as Mazon Creek, in the United States. The fossils from this region are around 300 million years old and come from the Carboniferous period. Around this time, the sea level was high compared to the current sea level. Large parts of Europe and America were flooded and existed were swamps flourished. The earth also looked very different. In the north lay the continent Euramerika consisting of Europe and America. In the south lies the continent Gondwana, consisting of Australia, Africa and South America. The plant fossils found in Mazon Creek have probably lived in a river delta near the equator. The fossils were well preserved because they were quickly covered with a thick layer of sand.
