gcaruso Posted August 30, 2014 Share Posted August 30, 2014 We decided to take a drive to the Penn Dixie site today. It was a nice family outing. I didn't find anything amazing but I did find a small fully enrolled trilobite, (possibly) one prone trilobite, one nice sized trilo body, some brachiopods, and tons of horned coral. (My five-year-old loves the horned coral so we now have boxes of it!) I think this guy is all there! I won't know until I start to prep it. Here's a nice body: Link to comment Share on other sites More sharing options...

Auspex Posted August 31, 2014 Share Posted August 31, 2014 Well done! Penn Dixie is such a fantastic resource, especially for family excursions.

squalicorax Posted August 31, 2014 Share Posted August 31, 2014 Hey Gary! Did you post that nice one malcolm prepped for you? My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...
RickNC Posted September 1, 2014 Share Posted September 1, 2014 I went there last year while in the area visiting my in-laws. It was an interesting place and something much different than I am used to down here. I brought back a lot of fossils that hopefully somebody I will be able to prep.

gcaruso Posted September 3, 2014 Author Share Posted September 3, 2014 Thanks for the invite! (BTW, my name is Gregg not Gary) I'll see if I can make it. I really do love Penn Dixie. It's a great place to take my daughter and I tend to find great things there. Gregg Link to comment Share on other sites More sharing options...

Fred Posted September 3, 2014 Share Posted September 3, 2014 The specimen in your second picture seems to be a case of a 'salterian' molt. Pacopids have the habit of throwing off the cephalon shield and crawling out. The cephalon can often be found upside-down in the vicinity of the thoracopygidium. The one you show here seems to be a textbook example. Fantastic! 1 Paleo database, information and community Link to comment Share on other sites More sharing options...

gcaruso Posted September 3, 2014 Author Share Posted September 3, 2014 Fred, that is great to know! Thanks for the info. Like Tim, I'm learning something new everyday. Link to comment Share on other sites More sharing options...
gcaruso Posted September 3, 2014 Author Share Posted September 3, 2014 P.S. So looking at the picture again, do you think that's the cephalon shield on the top rock? If so, that's cool to find a fossil capturing the process. Link to comment Share on other sites More sharing options...
Fred Posted September 3, 2014 Share Posted September 3, 2014 Yeah, I believe it is. If you're lucky, all of the shell is in the same slab and a careful ventral preparation of the cephalon would make for an interesting conservation piece.

piranha Posted September 7, 2014 Share Posted September 7, 2014 That diagram was only one snapshot of the entire phacopid exuviation process. The end result shows the cephalon flipped over, but the actual juxtaposing can vary quite a bit. Here's the entire sequence showing the trilobite in inverted and upright positions prior to exuviation: original figure is from: Speyer, S.E. (1985) Moulting in phacopid trilobites. Transactions of the Royal Society of Edinburgh, 76:239-253 illustration redrawn in: Bonino, E. & Kier, C. 2010. The Back to the Past Museum Guide to Trilobites.
