Too bad you didn’t have electricity and couldn’t put a couple fans and heaters on the thing. Good summer Texas sun and heat would have done it wonders, but then you couldn’t wait that long. I keep my eyes down in the bed most of the time, or on the red layer. Guess I need to look up some too. I have never seen anything in the upper layer when I have looked though. Hum, Pleistocene, that may be the answer to a fossil ID post I just made about something I found yesterday in the NSR. On the smaller tusks and various bones and teeth I’ve hauled home, I’ve found that accelerated drying sets up stresses that exacerbate cracking. Given the luxury of bench prep on Pleisto vert stuff, I tend to allow natural, slow drying, arresting cracks twice a day with superglue, then immerse in thin Butvar solution before fully dry (and fully cracked) at perhaps the 2 day mark, then allow several more days fo full drying, finally wiping off any white, moisture-induced haze with a shot of pure acetone. 1 Grüße, Daniel A.

I get that, but would it have been better to cracked tusk vs tusk soup? Of course in that state it may have ended up as tusk dust if dried too quickly.

Hum, Pleistocene, that may be the answer to a fossil ID post I just made about something I found yesterday in the NSR. I'm not sure drying would have helped keep it together though, unfortunately. What seems to have happened is that all of the concentric rings that make up the tusk, over time, probably grew and shrank with the clay (drought/flood cycles) which caused each ring to fracture. When it moved all of those fractures basically made it a fluid flow of tusk fragments. Any damage in the tusk was just spilling its guts. Bottom line, at 300+ pounds it needed to be completely and entirely immobile, which the plaster jacket didn't provide enough of that (probably partly at my fault) Link to comment Share on other sites More sharing options...

A good montage of photos was my personal best hope once we noted the compromised condition of this thing. Could be my biggest vert find ever, and now it is a matter of public record. Still, I wish this one was dominating a whole room at Anthony’s house. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."

Jacket. Bond lumber superstructure to jacket to lock out any and all axial, flexural, and torsional degrees of freedom and resulting deflections in response to shifting quasistatic and shock loads inherent to handling.
