Clonograptus trochograptoides Harris et Thomas, 1939
To the right is a wonderful specimen of Clonograptus trochograptoides Harris & Thomas, 1939 from the Bendigonian of Victoria, Australia: a disc shaped rhabdosome involving at least 11 orders of dichotimy. The dichotomies are spaces in such a way that an approximately uniform distance is maintained between stipes.
From R.C. Cooper.
