    Ok here’s my second cow skull and having same issues as last one. How do I keep the nasal and temporal together. I can wet the skull and the seam goes back together but I can not keep it together. I’ve tried bar clamps and rope but it will eventually open back up.

    elmers glue, zip tie that sumbitch together as it dries and then once dry wrap a string around it and twist a stick in it until the bones all come together and line up then take small paint brush and use white elmers glue all on the inside and glue together once dry remove string and repeat on outside.

    So I need to wet the skull and let it seal up, then put elmers glue on it while it's wet? Just trying to make sure i understand. thanks

    no, if you have to soak the skull to get it to go back together, do so and while still wet zip ties around muzzle to hold together while it dries, then after dry use a string and a stick around muzzle to force the suture closed more and then apply glue inside the muzzle along suture line and let dry. once dry remove string and apply glue on the the suture line on the outside. If you sue a brush and spread the glue out , most, if not all of it will absorb into the bone and be invisible.

    Pretty much as above. While the skull is still wet, I use strong furniture clamps on several spots along the length of the skull. Zip ties work on the narrow sections. As it dries. if I see movement, I clamp it tighter. Leave until completely dry. Remove the clamps and the suture will open a bit. Get Elmer's glue down into the open joint as much as you can and clamp it tight again. If some of the glue squashes up out of the joint I wipe it down level with a damp, clean rag. As it dries, if the gap will allow more glue to be added, I put a little more in there. Keep it clamped as tight as you can and leave it for a week until you are positive the entire thing is dried through. If clamps slide off I also take a lightweight rope like clothesline, make a loop around the skull, put a decent stick/dowel through the loop and start twisting like a tourniquet. Doing do will force the gap closed, sometimes even better than clamps depending on the shape of the skull. Secure the stick somehow so it doesn't unwind while it is drying.

    Sea Wolf I will give the furniture clamps a try...the zip ties didn't work for me, except down near the nasal opening...the skull split right up the middle again when it dried out. I'll see how it goes with the clamps.

    I've never had zip ties not work to keep it close, I then tighten with string and stick like mentioned after it is dry and glue. Was that skull boiled? I have gone to maceration exclusively and have less issues with skulls opening up.

    Skull was macerated and never in water over 90deg. This is the 2nd one that has done the exact same thing. I have big and little zip ties all over it as tight as I could get them and it still separated when it dried. I'm going to rehydrate and put some bar clamps on it and see how that works. I appreciate all the advice from everyone.

    After it has dried and you take the clamps off, if the cracks open upagain, get Elmer's down all the way into the cracks, all along the length of the crack and then clamp it back tight again. Leave it to dry for a week before taking the clamps off to make sure it is fully dry. Don't be in a rush. The Elmer's should hold it for good. ... unless it gets wet again.
