Yorgiidae is an extinct family of cephalozoans, which lived 635 million years ago. [1] They were filter fed. [2]
Like most proarticulates, they present semi- bilateral symmetry. They had a discoid appearance, with the body segmented by isomers.
Ediacaran of Russian Federation and South Australia. [1]
