Petalocrinus

From Paleos

Petalocrinus was a genus of crinoids from the Silurian. They are extremely distinctive from most, if not all other crinoids, in that their arms were modified into relatively large, wedge-shaped plates that gave their owners a decidedly flower-like appearance. All though the genus did not live out the Silurian, it was quite successful, with at least 15 species found in the United States, China, and Sweden (primarily from Gotland).

P. mirabilis is the type species, with specimens found in Iowa, British Columbia, and Yunnan province in China.
