Non-vertebrate paleontology collections

Other problems in the collections
. . . or "collection taphonomy"

Dust is only one of the problems we must find ways to combat.  Here is a sample of the other problems that we have identified so far.

cracking crab carapaces
Cracks caused by changes in humidity

Excluding air and water from pyritic specimens. Silica gel acts as a dessicant.
Preventing pyrite decay with silica gel

pyrite alteration leading to disintegration
Crumbling though chemical changes

silverfish demolish many old labels
Attack by silverfish

Total collapse of the specimen following internal decay.
Disintegration of specimen

The number is just fine..but where is the specimen?
In this case, the number has lasted longer than the specimen!
