Birmanites EXECEEDINGLY RARE Russian Trilobite

Description: A fine, well-inflated example of an exceptionally rare member of the Asaphidae, this is a trilobite of the genus Birmanites. The region in which these trilobites lived was subject to dramatic changes in salinity and turbidity, and the trilobites were able to make rapid (geologically speaking) evolutionary adjustments. These adjustments were thought to be able to allow them to see both predator and prey more easily. This taxon is quite flattened in aspect, a trait which most likely allowed it to hide just below the seafloor surface. It is the FIRST such example I have seen in FOUR YEARS, and serves as the representative of its type in a new book on trilobites of the region which is under preparation. As such, it would make an exceptional example of the diversity of trilobites from this region of Russia, sure to become the highlight of any collection.
