Sammajamma Posted September 16, 2022 Share Posted September 16, 2022 My son picked this up while visiting his grandpa. We aren’t sure but know it’s probably a concretion. Would love it to be a real egg! Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 16, 2022 Share Posted September 16, 2022 Hello and Welcome to the Forum. We would love for it to be a real egg as well, but, unfortunately, it is a concretion. There is no egg shell texture present. Please have a look through our Egg Guides. 1 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

FossilDAWG Posted September 16, 2022 Share Posted September 16, 2022 Welcome to the Forum! It's a concretion, but it does seem to have something inside (2nd photo). Worth splitting open I would think. You could give it a few taps with a hammer (not too hard) and see if you can get it to split lengthwise. I'm guessing it's a double Baculites, but who knows until you look. Don 1 Link to comment Share on other sites More sharing options...
Sammajamma Posted September 16, 2022 Author Share Posted September 16, 2022 My son asked me to post to triple make sure we aren’t breaking into an egg since we keep uncovering something Link to comment Share on other sites More sharing options...
Phos_01 Posted September 17, 2022 Share Posted September 17, 2022 (edited) Its a lovely stone suggesting an egg, but its not a Dinosaur egg im afraid, there is no egg shell visible , and the location does not match. It resembles an Oviraptor egg . I can image your thrill once you find a stone shaped like this. The links provided up are very useful in learning how an egg looks like edit : Perhaps a fossilized fruit? im no expert at this, but im sure some perhaps are here. All tough I have not seen them from Montana. Goodluck Edited September 17, 2022 by Phos_01 Link to comment Share on other sites More sharing options...
RJB Posted September 25, 2022 Share Posted September 25, 2022 Oh man! You have a lobster!!! Its your concretion but I would not break any more!!! You need to save each and every piece of rock and prep it out. RB 3 Link to comment Share on other sites More sharing options...
RJB Posted September 25, 2022 Share Posted September 25, 2022 It appears to be paleonepherops? I know its not hoploparia but there is also another one i cant remember. Is this from the Bear Paw? That info would help. RB 1 Link to comment Share on other sites More sharing options...

jpc Posted September 25, 2022 Share Posted September 25, 2022 I agree... Montana Cretaceous lobster. Now what to do with it? RJB suggested prepping it, but these things are notoriously difficult and time consuming. But they are cool. 1 Link to comment Share on other sites More sharing options...
Sammajamma Posted September 25, 2022 Author Share Posted September 25, 2022 Whoa! Thanks guys I’ll let my son know! We definitely opened it more but will try to see what kind of pictures we can post another update Link to comment Share on other sites More sharing options...
Ludwigia Posted September 25, 2022 Share Posted September 25, 2022 @Sammajamma If you plan on getting more of the lobster exposed, then I would advise you to first leave it as is and find someone who knows what they're doing to do the work for you. As jpc, one of our professional preparers has already mentioned, these are notoriously difficult to prepare and you may end up damaging it. Greetings from the Lake of Constance.

RJB Posted September 26, 2022 Share Posted September 26, 2022 Yep, these have been some of the tuffest preps I've ever done! Damage has already been done to this one and if trying to expose more, then more damage will happen. I'm not kidding when I said each and every piece should be saved so it can be repaired. That included not just lobster pieces but rock pieces also. This has the potential to be a high dollar fossil. Would be a shame to see it headed to the rock heap.

RJB Posted September 26, 2022 Share Posted September 26, 2022 @Sammajamma Here is a picture of what this has to potential to turn into with some really good prep. Good luck whatever you do RB 4 1 Link to comment Share on other sites More sharing options...
Fin Lover Posted September 26, 2022 Share Posted September 26, 2022 It's quite impressive that you guys can see such a small amount and know that it is a lobster! 1 Fin Lover My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

jpc Posted September 26, 2022 Share Posted September 26, 2022 As we like to keep things legal here, I would shy away from calling this a big dollar item, as almost all of these come from BLM land in northeast MT and the BLM does not allow selling of fossils found on their land. But the big dollars will come in how much time is spent prepping it. 1 Link to comment Share on other sites More sharing options...
rocket Posted September 26, 2022 Share Posted September 26, 2022 wow, what a cool find... rare Pleasepleaseplease, let someone who knows how to do do the prep-work. By opening with an hammer it could be destroyed... Link to comment Share on other sites More sharing options...
crabfossilsteve Posted September 26, 2022 Share Posted September 26, 2022 Gees, the whole string of crab/crustacean preppers have already chimed in to say yes its a lobster and please treat it nicely. We'd all lust after it...ha ha. Link to comment Share on other sites More sharing options...
