Microbrachius dickiDescription: This is a diminutive Antiarch known as Microbrachius . The Antiarchs were most likely bottom dwellers whose ventral mouth was well-positioned for feeding on benthic organisms. Note the very good preservation seen here and highlighted in the interpretive figure to the right. To date no specimens have been found with a tail. Given the quality of preservation of Eday specimens, it may well be that it did not possess one. See my other offerings for other Antiarchs.
