Ainiktozoon

Ainiktozoon loganense ("enigmatic animal", from αἰνικτός (aíniktós, "riddling, enigmatical")), is a fossil animal from the Silurian of Scotland.[1] It was found at the Birk Knowes site, part of the Patrick Burn Formation, near Lesmahagow.[2] Originally described as an early chordate,[3] recent studies suggest that it was in fact an arthropod, more precisely a thylacocephalan crustacean.[2]
