A few years ago my school went on a field trip to Calvert Cliffs in Maryland. From what I was told many types of fossils were uncovered there. While everyone else was looking for fossils, I was skipping stones. But I picked up a rock that had some weird disformities to it and upon taking a closer look, I realized that what I was looking at was a rib cage, or at least part of one. I had no idea what to think so I kept it. Getting ready to move, i found it again. And was wondering if anyone on here has any idea what this animal could have been(linking a picture of some sort), or if they have any ideas on how I can extract the bones from the stone without harming the fossil itself. Any help/ discussion will be greatly appreciated. Thank you so much!
I've just come back from a trip to Yorkshire where I managed to do a little fossil hunting and was lucky enough to find this ammonite. The problem is though is that generally the preservation in the area wasn't great and this one is clearly covered in a mudstone/ shale type of rock. However I think it might be worth trying to remove the surrounding rock because the small bit which I can see seems to have preserved fairly well. However I don't know the best way to remove it, see i'm not very comfortable with chiseling it away because I'm fairly new to this so would probably end up ruining it! I've been told that it may work if I was to put it into the oven to warm it up and then put it into cold water which could 'shock' the fossil to break along lines of weakness but I'm not sure if it would work or not. I've tried to post a picture of the fossil here but I'm not sure if its worked so if not here's a link: http://s1069.photobucket.com/user/zozzy-zebra/media/IMG_0003_zps69eb4cbf.jpg.html Any suggestions of how I can remove my ammonite would be greatly appreciated. Thanks
