PRK Posted December 20, 2012 Share Posted December 20, 2012 (edited) Well looks like its time for a new post. please keep in mind MOST, of my collecting adventures were before the "digital" age, so a lot of my pics are reprints from photographs. Dadgumit !!! if i only knew----.HOWEVER, most of these fossils ARE in my collection. The pieces I'm showing in this thread are very recent pics. The vast majority of this Cambrian material(lathem shale) i collected was also given to the museum before my move north these are pics of Olenellus clarki. The larger single trilo even has its opisthothorax preserved, a very rare occurrence Part A below----------------------------------------------- I call the one in the last pic," SPACEMAN" Edited July 8, 2013 by PRK Link to comment Share on other sites More sharing options...
trilobiteruss Posted December 20, 2012 Share Posted December 20, 2012 Very nice specimens. Love the slab with multiples! Russ Link to comment Share on other sites More sharing options...
erose Posted December 20, 2012 Share Posted December 20, 2012 Very nice. Scanned photographs can be great since most photographs are at a way higher resolution than what a video screen can show. Link to comment Share on other sites More sharing options...
PRK Posted December 20, 2012 Author Share Posted December 20, 2012 (edited) A nice Olenellus fremonti. However I think its genus has been renamed . Edited December 21, 2012 by PRK Link to comment Share on other sites More sharing options...
PRK Posted December 20, 2012 Author Share Posted December 20, 2012 (edited) A very nice, and large, mass cephalon plate. Which even tho is very flat, probably indicates a slight depression in the mud where molted trilo parts accumulated within Edited October 8, 2013 by PRK Link to comment Share on other sites More sharing options...
PRK Posted December 21, 2012 Author Share Posted December 21, 2012 (edited) A superbly preserved pygidial section. Only approx a centimeter in length, without the tail spine, And a very tiny cephalon. So small it missed being compressed flat by time and millions of pounds of pressure during the looong lithification process. Approx, 2.5mm Edited July 23, 2013 by PRK Link to comment Share on other sites More sharing options...
piranha Posted December 21, 2012 Share Posted December 21, 2012 A nice Olenellus fremonti. However I think it has been renamed since I collected this That one is Mesonacis fremonti... congrats on the great find Link to comment Share on other sites More sharing options...

PRK Posted December 21, 2012 Author Share Posted December 21, 2012 (edited) Hers a couple more O. Clarki. They too stayed in LA. The black and whites were taken by a good photographer friend back in the '70s. He went totally blind within a few months of taking these photos, and subsequently passed about a year later. He was a Vietnam vet, and was another domestic casualty of agent orange. Ill never forget Richard. Nice guy. Edited January 3, 2013 by PRK Link to comment Share on other sites More sharing options...

Missourian Posted December 22, 2012 Share Posted December 22, 2012 Have you collected any archaeocyathids from that lower Cambrian? Context is critical. Link to comment Share on other sites More sharing options...
PRK Posted December 22, 2012 Author Share Posted December 22, 2012 (edited) None that I know of. although just becuase I didnt find one doesnt mean they arent there. I do however have some very interesting ?????s, and parts of several of the more unusual trilos also. the more exotic trilos were unknown back then but NOW there are over a dozen varieties known from the lathem shale, along with many more types of animals Here's a lower cambrian whatzit from lathem shale Mohave desert calif Edited December 22, 2012 by PRK Link to comment Share on other sites More sharing options...

Wrangellian Posted December 23, 2012 Share Posted December 23, 2012 The trilo quarry. Note how the previous collector dumped his waste talus right on top of a VERY productive pocket of trilobites. ARGGGGGG!! the lathem shale, trilo producing, marble mountains I guess he was trying to hide that productive pocket from others. Link to comment Share on other sites More sharing options...
PRK Posted January 2, 2013 Author Share Posted January 2, 2013 (edited) Most trilos I find at the marble mountains cambrian lathem shale, the entire dorsal shield is usually not much more than a couple inches. However on my last trip there I found evidence they get much larger. This interesting cephalon is not complete, probably due to the molting process, but shows the incredible size these trilobites reached in the cambrian Lathem shale of calif. I saved this fragment because it represented such a extreme size. I think it extrapolates out to over 6inches across. ill post one more below for now.

PRK Posted January 2, 2013 Author Share Posted January 2, 2013 (edited) So here is the other I promised. A lovely pair of well preserved cephalons. although I consider these to be very large, and well preserved, they are nowhere near 6+ inches. Note: the cambrian shale is quite uncooperative, and doesn't tend to split into large, even, plates properly.

Like everything else you've shown us. Amazing that you could give so much to museums, yet still have a world-class collection. Don Link to comment Share on other sites More sharing options...
PRK Posted January 3, 2013 Author Share Posted January 3, 2013 (edited) I AM A DIGGER!!! i felt the museum should have the local fossils. So I gave the museum loads of good local stuff I didn't want to move, as I was off to a new life and new hunting grounds. But as you can see,I did keep some stuff tho.

Wrangellian Posted January 4, 2013 Share Posted January 4, 2013 May be uncooperative shale, but it still doesn't look as bad as the stuff I have to work with! Impressive piece anyway. I have a large cephalo and a large thorax/pyg from Cranbrook BC (not self-found) that are also quite large. I should get pics sometime... Link to comment Share on other sites More sharing options...
PRK Posted January 15, 2013 Author Share Posted January 15, 2013 Another Unusual soft body cambrian whatzit. Anybody have any ideas? Link to comment Share on other sites More sharing options...
piranha Posted January 15, 2013 Share Posted January 15, 2013 (edited) Another Unusual soft body cambrian whatzit. Anybody have any ideas? There are worms described from the Latham Shale but I think this might be Lathamoserpens (Latham Shale "serpent"). I found a paper describing this possible curved hyolith, although there is ample debate among the reviewers on its true affinities.
