    I have a possible bryozoan I want to clean up. maybe remove some of the limestone matrix. I’m not sure the best way to do this. The spaces are very small between the branches.  I could use some good tips. I know I can use acid. The tubes look hollow.

     

    Cheers

    I’m new to the group.

    I have prepped bryozoans and other specimens with really tiny spaces. Acid kinda works but it also affects the actual fossil a bit which I figured was counter productive. The best ways I found were either with a fine tipped dremel point (that too could damage the surrounding piece) or the old fashioned way if the material is soft enough…a safety pin. Plan to work on it over a longer period of time because your hand/fingers will get tired.

    Every now and then a quick dunk in light acid solution (10% muriatic acid?) to see where things stand.
