Fossil of an ancient creature "fossil crinoid"

Many fossils of ancient creatures and plants have been unearthed in Rokando, which was created in the geological formations about 300 million years ago. Among all the fossils excavated here, the fossils of sea lilies are the most commonly found.
Sea lilies are flower-like creatures that are members of the echinoderm family such as sea urchins an d starfish.
Today, they still live in various marine environments such as coral reefs, deep sea, and shallow water, and are said to play an important role in the marine ecosystem due to their unique ecological characteristics.
Generally speaking, sea lilies are difficult to fossilize, but there are many of them dotted around Rokando, so please try looking for them.
