erik m Posted April 22, 2011 Author Share Posted April 22, 2011 He Erik, has this something to do with your work? Wally Hi Wally, No it is a fossil I only made the Xsection on my work this one is not so hard to find out what it is. Greetings Erik Link to comment Share on other sites More sharing options...
ElGastropod Posted April 22, 2011 Share Posted April 22, 2011 (edited) Hello from the Netherlands also, I was trying to find what is an Xsection and I found this is not the first Xsectin quizz you offer to the forum ! So first a non-fossil question to try to understand what I see in your pictures. What is an xsection? How do you have to prepare the samples? Just realized Xsection = cross-section, I am definitely really slow... So I change my question... How thick are the samples and what type of light are you using ? Is it in transmission ? Thanks, Pierre Edited April 22, 2011 by ElGastropod Link to comment Share on other sites More sharing options...

Thanks, Pierre Hi Pierre, A Xsection sample can be from a few MM to 15 CM big and it can be just a few micron's thick. It is possible to make bigger on's but than the grinding machine has to be bigger. It depends what you whant to make a Xsection of. The photo's are made with a optical microscoop and the blue coller is done with a nermansci filter. You can bend your licht bundel with this filter it almost like a polarization filter The two foto's you see now are from a verry thin piece of shark tooth. But back to the question whats on the firts set of photo's Link to comment Share on other sites More sharing options...

Crinoid Queen Posted April 22, 2011 Share Posted April 22, 2011 Just for the fun of it what do you see. A tooth of some kind? Looks like microscopic bone ostiocyte and the one is kinda shaped like a shark tooth. Link to comment Share on other sites More sharing options...
ElGastropod Posted April 23, 2011 Share Posted April 23, 2011 Could 2 and 4 be cross-sections of a bone ? It is just a guess from trying to match them with fossil cross-section images found on the net... http://www.geo.ucalgary.ca/~macrae/t_origins/carbbones/dino_bone2.jpeg Pierre Link to comment Share on other sites More sharing options...
jpc Posted April 23, 2011 Share Posted April 23, 2011 I also think 2 and 4 are bone X-sections. And the blue one is the cover art from The Who's classic album Tommy. Link to comment Share on other sites More sharing options...

Diplotomodon Posted April 27, 2011 Share Posted April 27, 2011 A X-section of something that looks really pretty under a microscope. What a wonderful menagerie! Who would believe that such as register lay buried in the strata? To open the leaves, to unroll the papyrus, has been an intensely interesting though difficult work, having all the excitement and marvelous development of a romance. And yet the volume is only partly read. Many a new page I fancy will yet be opened. -- Edward Hitchcock, 1858 Formerly known on the forum as Crimsonraptor @Diplotomodon on Twitter Link to comment Share on other sites More sharing options...
erik m Posted April 27, 2011 Author Share Posted April 27, 2011 Hi All, These photo's sould make it easy to see what it is. I did make a few photo's where you can see more of the fossil. The firts photo show's the spot where the piriet is. And the other photo's sould say it all. This fossil is fond in the Netherlands.
