RE: paleonet Fossil terminology

["Kristen Myshrall" <trilobitegirl@xxxxxxx>]

Hi Michel,

A composite mold combines both internal and external features on the same 
surface. Essentially a composite mold is formed when both of the internal 
and external surfaces are compacted together resulting in composite 
impressions on the same surface. Sort of like a combination of an internal 
mold and an external one.

Hope this helps,
