Notidanodon Posted October 27, 2018 Share Posted October 27, 2018 How should I fix the broken tooth and stop the rock from crumbling also any help on identifying the fossils would be appreciated (apart from the mosasaur tooth Link to comment Share on other sites More sharing options...
Darktooth Posted October 27, 2018 Share Posted October 27, 2018 That is really a great piece. Looks like you have a Mosasaur vert, shark vert, Squalicorax pristodontis tooth, along with the mosasaur tooth. As for the broken tooth could it be another mosasaur? Is this completely broke or do both pieces still stick to the matrix? I don't know about how to stop the matrix from crumbling but it looks really nice. It will be a nice and interesting display. 1 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Ludwigia Posted October 27, 2018 Share Posted October 27, 2018 I'd have a careful go at it with a pin vise and have a tube of fluid super glue handy in order to harden the parts you don't want to crumble. As to the broken tooth, you would need to separate the 2 parts, clean off the ends and realign them before you glue them back together. Nice acquisition! 1 Greetings from the Lake of Constance.

Thanks, the very bottom fragment of the tooth is detatched from the matrix but the top is still connected the crumbly matrix is a problem though as it is very hard to glue to shall I apply varnish or sonething like that Link to comment Share on other sites More sharing options...

Notidanodon Posted October 27, 2018 Author Share Posted October 27, 2018 Ok thank you I was just wondering as moisture caused it to crumble much faster so I thought that I could seal it off with non shiny varnish to stop the transfer of moisture 55 minutes ago, Darktooth said: I don't know about applying varnish lets see what others have to say about that.

Things like Paleobond and Butvar are discussed often on the forum. @Haravex probably can give insight as he has hunted in Morocco and am sure has dealt with this issue in the past.

Ptychodus04 Posted October 28, 2018 Share Posted October 28, 2018 Varnish is evil for fossils. It’s bad in every possible way. Go for a bit of Paraloid as it will stabilize the matrix well. It can be had rather inexpensively and dissolved in acetone. Brush a couple coats on the matrix (after you do any cleanup) and you’ll be in good shape. 1 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...

Haravex Posted October 29, 2018 Share Posted October 29, 2018 I've never actually prepped any phosphate material however it looks to be relatively soft matrix try dental picks and brushes the cheap make up ones you can get work really well. I would start by removing the matrix from the obvious need cleaning areas such as what is obscuring you viewing the fossil. Next would be stabilise the bulk of the matrix what is holding all the fossils together I would recommend using paraloid b72. Now for the tooth you can leave it as is however once you have done all these steps carefully extract the broken tip by removing excess matrix and reattaching using a good strong super glue. Again I'm not a professional but am an enthusiast and learning as I go there is to my knowledge no hard or fast rules when it comes to prep work, with that said I hope this is some use and help to you. Thanks Matt 1 Link to comment Share on other sites More sharing options...

snolly50 Posted October 30, 2018 Share Posted October 30, 2018 I thought I had already commented on your very nice specimen, but I see I did not follow through. It is a nice display piece in that it shows a variety of fossil types. If it were mine I would not dislodge the large crown from its resting place. I think the piece displays well with components in situ. I would only do minor prep. Just a little clean-up/uncovering. A needle and pin vise will do very nicely with the granular matrix. For consolidation with an acetone based material, be aware that breathing acetone is not a good idea. So be mindful of proper ventilation. Below is my old post you may find interesting. It is obviously the cousin of your piece and the matrix shown there should work very much like yours. Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See Link to comment Share on other sites More sharing options...
Rob_P Posted November 1, 2018 Share Posted November 1, 2018 Personally I’d clean up around the vert so it stands out a bit more and clean the debris looking matrix and keep it as a whole display piece. Link to comment Share on other sites More sharing options...
