While out on a hunt in the Marias River Shale (Cretaceous) near Fort Benton, MT, I found what I believe to be either a holoscaphites or clioscaphites, based on the research I have done. The rocks in the exposure are quite segmented and eroded and don't take much force to break apart; a few small taps from my hammer made the rock, and the fossil inside, essentially fall apart into several pieces. My question is not one of ID, but rather of how to best prepare this fossil. From looking around this forum, it seems that many people use super glue for repairs that aren't very large. Would super glue be smart to use here, or should I order some Paleo-Bond? My best guess is that this fossil is only about 10 cm across or so, but it's hard to tell because it's in pieces. I am also about 95% sure that I got all the pieces, but I'm sure there's small fragments missing here and there. Is it important/necessary to fill in missing bits with epoxy, clay, etc.? My next question is about the white powder that covers this fossil. Most every fossil I found still in matrix had some amount of white powder on it, so I can assume it's either part of the shell or a chemical/geological effect of the fossilization process. Is this powder important to the integrity/aesthetic of the fossil, or is it something that can/should be cleaned/removed? There are some very neat internal structures visible on the breaks, plus some crystallization. The white material rubs off at the slightest touch. I have tried my best to minimize how much white comes off the main segments (this one was a swipe off a piece of the negative). I have not done anything to this fossil except attempted to fit the larger pieces together to make sure I'm not missing any other major pieces; I've already made one return trip to the site to recover some bits that I know I left behind the first time. Please let me know if I need to upload more pictures. I would love to repair this gorgeous ammonite and do it justice by not destroying it even more. Thank you!

Hey everyone! I have a ton of fossils from a recent trip to the White River Formation and I need to start prepping them. Unfortunately, I don’t have an air abrasive unit, but I have started to get the supplies. So far, I have an air compressor and a sand blaster. (Sand blasting cabinet) The last piece I need is the tank to hold and connect the powder to the sand blaster. Where should I look to get one? Any response is appreciated! Thanks!

I'm currently experiencing some issues with a brand new central pneumatic air eraser where when I hook it up to an air compressor: 1) air either blows through the air eraser without carrying any powder from the reservoir regardless of whether or not I'm pressing the control button or 2) air simply doesn't blow through it at all I've tried adjusting the screw on top of the reservoir and I've also tried to blow any powder that's stuck on the inside that may be gumming it up but these fixes have not worked. Has anyone else experienced a similar problem? If so, how did you fix it? I've only been using this instrument for two days for spraying MgO powder onto trilobites for photography.

Hello all. I recently picked up this Airbraisive which has a quite large "industrial" nozzle that's orifice is WAY to large for me ! I'm using 44u CrystalMark dolomite as well as some CrystalMark soda. Any thoughts on upgrading the handpiece and or just nozzles. Sizes, etc.? Thanks in advance.
