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

Date: Thu, 09 Nov 2006 09:44:23 +1000

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'm tempted to call it "an Adam's Navel taxon".
