Hans-Martin is interested in the Late Devonian fishes of the Bergisch-Gladbach and in addition is working on Lower Carboniferous carbonates from Belgium. He has found a rich microfauna which includes teeth of Bransonella.

While I'm sorry to say that I don't know of any Cladodusspecimens that have more than the teeth preserved, I would like to say thanks again to those who helped me with my Cladodus/form taxon problem earlier this year. My senior thesis is FINALLY done! The title of it is "The Fauna and Paleoecology of the Burlington Formation (Mississippian) of Missouri, with a focus on Chondrichthyan Ichthyoliths" If anyone is interested in a copy, let me know...I did devote a small chapter to the status of Cladodus.

We continue to find amazing things in our samples from the MOTH site, but most of the new undescribed species are coming in the acanthodian and problematic heterostracan areas rather than in the thelodonts. Nevertheless I'm still very interested in the fork-tails. The more I work with them the more I think they share something special with pteraspidiforms.
I've got a couple of undergraduate students doing projects on cephalaspids these days. One of them is zeroing in on the sandy filling of the inner ear that we see in cephalaspids, acanthodians, and putative chondrichthyans at the MOTH site. It also occurs in acanthodians at Miguasha.
