<p class="MsoNormal">Hi Beth,<o:p></o:p></p>
<p class="MsoNormal">I agree with Aren, the bear cubs will make nice study skins + skull/skel. You can do flat study skins and just put cardboard in the skin with some cotton wrapped around the cardboard. We don’t have any bear skins at UMNH, but I attached
some photos of badgers that were prepared flat and they store nicely. If you’re concerned about space, you could also just save the skull/skel and a mask. So for a mask you just keep the skin from the face and pin it out flat to dry (fur side down on the board).
This is typically what I do with large adult carnivores. I’m not a proponent of tanning because some tanning processes substantially degrade the DNA in the skin making DNA recovery nearly impossible. I assume you’re taking tissue as well, but say the tissue
gets lost or used up, you could still extract DNA from dried skin. Also not sure if tanning compromises the fur in any way if someone wanted to do stable isotope analysis on hair.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Since you have four of them, you could do a few different prep types so they could be used in different ways. Perhaps just do one cub in fluid?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Good luck! Sounds like a fun project!<o:p></o:p></p>

<p class="MsoNormal">Hi Beth,<o:p></o:p></p>
<div>
<p class="MsoNormal">We have many standard study skins of young bears. There is no need to tan the hides. Skin them as you would a squirrel or vole. Wash the skin with dish soap to remove grease, then towel dry. We use bamboo skewers or wooden dowels instead
of wire, for large skins. Blow out the hair with lab compressed air to push any water out of it and to fluff it up. After pinning the skin, insert the compressed air into the mouth and a hind foot to push some air through the skin while it dries. We have done
this with skins as large as adult lynx, coyotes, beaver, and wolf. <o:p></o:p></p>
