The ancient fossil biology set is 65 million years old.

The fossil set is found in South Dakota and North America cliffs. According to the biologist, these ancient fossils belong to free-swimming species, called Ammonites .

This species lives in the sea with methane gas and contains other chemicals such as hydrogen sulfide, dating back to the Cretaceous period, 65 million years ago.

Hypothetical scientists, Ammoties belongs to relatives of extinct ink Nautiluses. However, this hypothesis does not coincide with the 74 million-year-old ink fossil that archaeologists previously found.

Learning about Ammoties, experts say, bacteria living in the sea have methane and hydrogen sulfide, which are plentiful food sources of plankton.

Experts are continuing to learn more about the nature of this species. As expected, fossils will be transferred to the Natural History Museum (USA).

This new finding is published in the journal Geology - Geology (USA).
