Ainiktozoon loganense is an enigmatic fossil organism from the Silurian of Scotland.[1] Originally described as an early chordate,[2] recent studies suggest that it was in fact an arthropod, more precisely a thylacocephalid crustacean.[3]
A. loganense is known from a number of specimens from Silurian rocks (Ludlow series) at Lesmahagow in Scotland.[3]
Etymology
The generic name Ainiktozoon is Greek for "enigmatic animal", from αἰνικτός (aíniktós, "riddling, enigmatical").[2]
