pterosaur bones (perhaps Dorygnathus)
This is probably one of my best find so far from the quarry Kromer near Holzmaden.
Its a plate with some pterosaur bones, which is very rare in Holzmaden as these are marine desposits. The bigger bone might be a Humerus. Before I was able to find this piece I only found a few isolated pterosaur bones. Hopefully I can find a complete one one day
The prep of this specimen took about 5 hours. Before the prep it was visible that these are pterosaur bones so I was very surprised ...
