These are two crocodile vertebrae from the lower Jurassic (Posidonia Shale) from the quarry Kromer near Holzmaden.
The bigger one is about 8 cm long.
Here is a picture of the unprepped fossil:
The prep work took about 10 hours. I am very pleased with this find because in general crocodile bones are much rarer than Ichthyosaur bones in Holzmaden.
