Ptychodus04 Posted October 20, 2018 Share Posted October 20, 2018 @DLB Those are looking nice. Now that you have a lot of bone exposed, you can coat the exposed with Paraloid,PVA, or Butvar to further protect it from the acid wash. The acid will discolor the plastic but that’s ok. You can remove it with acetone when acid prep is finished. Well done thus far. 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...
RJB Posted October 20, 2018 Share Posted October 20, 2018 Yeah, what Kris said. You see, I can sound smart by simply agreeing even though I had no idea about it. and a hardy har har. RB 1 Link to comment Share on other sites More sharing options...
Haravex Posted October 20, 2018 Share Posted October 20, 2018 Forgive me for asking what might seem to be a very obvious question but with these fossils everyone seems to use acid prep why not manual with scribe and abrasive? Link to comment Share on other sites More sharing options...

The matrix is typically very hard and the bones are very small. The matrix composition is rather reactive with acid. The combination of all those factors makes acid prep the easiest and safest option for preserving fine details. Granted, most people don’t use the extreme method @DLB is employing. It is effective but if done wrong, bye bye specimen. 2 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...

DLB Posted October 26, 2018 Author Share Posted October 26, 2018 ya the detail is starting to come out alot more i just hope they all are as complete as the one thats allmost done.

I have a question do you know if they had live birth or have eggs? From good ole Wikipedia: Although there is no direct evidence, Keichosaurus was potentially ovoviviparous (eggs form and hatch within uterus). Fossil Keichousaurus display a simplified elbow joint and a lack of ossification in the olecranon process of the ulna. This would make crawling up the beach to lay eggs awkward. Specimens at different developmental stages, found in the same type of sediment at the same locality, also support an ovoviviparous reproduction model. However, fossils have been found of female Keichousaurus with fetuses within the lower portion of the thoracic cavity. Their position implies that they are not victims of cannibalism. 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...
DLB Posted October 26, 2018 Author Share Posted October 26, 2018 I ask because on the most complete one in the lower portion of the body there's a round egg-shaped spot and it's always been a little bit more porous than all the rest of the bone Link to comment Share on other sites More sharing options...

RB well its hard to tell since I spend a out 10 to 15mins a day working on them and the rest of the time the acid does all the work. But its been probably a month now. it would go alot quicker if it was nice outside here more its been raining alot. Link to comment Share on other sites More sharing options...
