Hazelia
Extinct genus of sponges
Hazelia is a genus of spicular Cambrian demosponge known from the Burgess Shale, the Marjum formation of Utah,[4] and possibly Chengjiang.[1] It was described by Charles Walcott in 1920.[5]
Its tracts are mainly radial and anastomose to form an irregular skeleton.[4] Its oxeas form a fine net in the skin of the sponge.[4]
