|  Description:
This is a very special offering of the second oldest trilobite species
ever discovered in the ancient continent of Laurentia. It is in
effect the oldest complete trilobite genus ever discovered in the
USA. The oldest is Repinaella; with never a complete one yet discovered.
Eofallotaspis has been recently discovered and described by Hollingsworth.
His scientific paper was published in 2005. A mere handful of these
have been collected, and the very small outcrop appears to be exhausted.
It is also the only one available. It’s an exciting and valuable
must-have for the specialist collector of L. Cambrian trilobites.
The trilobite itself was professionally prepared with air abrasion.
Unfortunately the specimen is not complete. The cephalon is in good
condition. While most of the left thorax and spines are in place,
the pygidium is missing.
