RE: when is a Lazarus Taxon not a Lazarus Taxon?

[John Scanlon <riversleigh@outbackatisa.com.au>]

Sorry if I missed this already, but is there a name for the time-inverse of
a Lazarus taxon, i.e. a newly discovered beast that indicates a long ghost
lineage BEFORE a group was known to have flourished?  An example would be
Pikaia when it was thought to be a chordate.

(I hope that's clear: the syntax of biostratigraphic discovery is almost as
difficult as that associated with time travel)
