From the album: Late Jurassic Ammonites from Southern Germany
ø 18cm. divisum zone Early Kimmeridgian Lacunosamergel Formation Lochen Subformation Sponge facies Found in the Upper Danube Valley With epizoan tube worms, sponges and a small attached ammonite. -
I took another trip yesterday to the Kimmeridgian site in the Danube Valley and continued my dig in the divisum zone. This time I came up with, among other things, a Pseudhimalayites uhlandi ammonite with a diameter of 18cm. These things can get quite large, so I'm dealing with just the phragmocone here. As I've mentioned in other posts, this exposure is in the middle of a sponge reef, so a lot of activity was going on here at the time that this creature hit the dust, so to speak. It landed on a group of sponges and began to deteriorate and deform, revealing the insides of some of the septa, but not before a number of epizoans, such as tube worms, colonized it, some bits of sponge got stuck to it, and another little ammonite shell dropped onto it before it was finally buried and retained for posterity. The photos below can be enlarged to have a better look at the detritus. Thought it might interest you.
