hrguy54 Posted July 30, 2013 Share Posted July 30, 2013 I've found these over the years, all 4 seem to be in a similar state. Please describe what's going on with them. I'd like to see others' that are similar. Link to comment Share on other sites More sharing options...
squalicorax Posted July 30, 2013 Share Posted July 30, 2013 I think number 1 is a burrowed piece the next two are large cephalopods with their siphuncle preserved inside My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...

Roz Posted July 30, 2013 Share Posted July 30, 2013 Your second image shows all kinds of hitch-hikers on it. Welcome to the forum! Link to comment Share on other sites More sharing options...
TMNH Posted July 30, 2013 Share Posted July 30, 2013 Yes the middle cylindrical portion is the cast of the siphuncle and the rings are casts of the camerae. Endoceras that I find here are often preserved in the same way with some of the camerae weathering off the end portions leaving only the sipuncle.

hrguy54 Posted August 5, 2013 Author Share Posted August 5, 2013 OK, but.....how might the cephalopod cast have gotten in this "condition"? Was the actual creature smashed, decaying, ??? when it was covered in sediment? Your thoughts? Link to comment Share on other sites More sharing options...
hrguy54 Posted August 7, 2013 Author Share Posted August 7, 2013 Is this stumping everyone out there or something that I should know already but no one wants to tell me? lol Link to comment Share on other sites More sharing options...
Auspex Posted August 7, 2013 Share Posted August 7, 2013 One thought I have is that sediment was able to fill the siphuncle, and a few breached chambers, but not adjacent chambers that were intact (but much, much later dissolved away).

squalicorax Posted August 19, 2013 Share Posted August 19, 2013 OK, but.....how might the cephalopod cast have gotten in this "condition"? Was the actual creature smashed, decaying, ??? when it was covered in sediment? Your thoughts? I think it died on the bottom and some of the chambers seperated from the siphuncle and washed away. They the entire cephalopod was filled with sediment rapidly and preserved. It is very common to see preserved cephalopods like this.
