Hello all, It's been a long time since I've been on here, but my interest in collecting Ontario trilobites has been renewed over the past few years. One of my goals has been to find a trilobite piece on a job site. I was near Port Hope last week and went to check out a fill pile on my break when I flipped over a rock and found this little guy. Since it was in a fill pile I have no idea what formation it's from, or its age, and so I'm having a hard time id'ing this specimen. I would appreciate any help. Thanks. Location: Fill pile near Port Hope, Ontario Age:Unknown Formation: Unknown Size: approx 1cm x 1cm

Looking for advice on how to repair a long bone with a missing center piece
uncoat posted a topic in Fossil Preparation
I just returned from a collecting trip and to my dismay i realized that i am missing a piece of a fossil bone i collected.. The bones at this site are in concretions and are not always visible on the outside so a lot of the time they have to be broken to know for sure what is inside. I thought i had a fairly clean break but when i got home and re assembled the pieces, it seems that one section of the bone is missing in the center. I have delt with small problems similar to this before by filling the missing space with Durham's putty and sculpting it on the edges. With this fossil, an entire section of bone is missing. So i will want to reassemble the rock and fill the section before i start in of prepping it so i know exactly how wide the space is. My concern is that something like Durham's wont be strong enough to support the full strength of the bone during and after preparation. Can anyone suggest a similar sculpt-able putty that would not shrink and dry incredibly hard? Since the concretion is in pieces its hard to photograph in a way that conveys what i mean so i drew a picture of the problem. Nick -
