Papers on 'Lazarus' species

["Bruce Woollatt" <brucewoollatt@hotmail.com>]

Hello all;

A few years ago I came across a paper on so-called "Lazarus"  dinosaurs; 
(dinosaurs whose fossils seem to disappear from the record but are found 
again in later sediments as if they had returned from the dead. Had the 
later fossils not been unearthed, the creatures in question would seem to 
have died out sooner than they in fact did.) This paper was part of a 
collection from one of the symposia on mesozoic terrestrial ecosystems held 
in the early 90's. (I will include more details if and when I come across my 
copy of the paper). My question is if anyone has done a follow-up of this 
study?

Thanks in advance,
Bruce Woollatt
