Hey guys do any of you know where I can find Some placoderms here in Black Hawk County Iowa? I have only found a plate piece here and some of my friends found some WHOLE PLACODERMS. while I only have one tiny plate. If you can help me please and thank you!
A group of us spent several days at a spot near Thedford, Ontario working an exposure in the Widder Formation. Rather than roll out a long backstory, I thought I would go straight for showing the finds. I'll kick it off with the trilobites. 1. A coveted multi-plate containing three Greenops widderensis. The picture is blurry because it was starting to rain that day and we had to move fast. As one of them had its lappets hovering precariously outside the matrix, I had to coat them in cyanoacrylate fast so that it would survive the trip home. This one is in the hands of a preparator friend as it may be a bit more advanced than my current skills could handle.
For those who have interest in Devonian placoderms here is a paper on Dunkleosteus terrelli Ferrón HG, Martínez-Pérez C, Botella H. (2017) Ecomorphological inferences in early vertebrates: reconstructing Dunkleosteus terrelli (Arthrodira, Placodermi) caudal fin from palaeoecological data.

Hi guys! A few days ago my dad and I went to Yass, NSW Australia. We went to two specific locations, and found placoderms, shells, nautiloids and trilobites. Don't forget the coral!
