is an exceedingly rare trilobite, and the second oldest trilobite
species ever discovered on the ancient continent of Laurentia. It
is, in effect, the oldest complete trilobite genus ever discovered
in the USA. Eofallotaspis is believed to be the ancestor of Eoredlichia
the Redlichiidae. The oldest is believed by trilobite workers to
be Repinaella, but a complete specimen has yet to be discovered.
This Eofallotaspis has been recently discovered and described by
Hollingsworth in 2005. A mere handful have ever been collected.
The trilobite itself was professionally prepared with air abrasion.
It is well preserved, inflated and complete. The tip of the pygidium
is slightly folded under.
