Paleonet: Hollis Hedberg's studies on Western Colombia

[German David Patarroyo Camargo]

Dear Paleonetters

I am trying to found the micropaleontological information that Hollis Hedberg obtained from the Western Colombian Cordillera at 80's. Unfortunately this valuable information is only published on internal reports of oil companies (EXXON may be) aparently and is completly unknow here in Colombia.

Actually this kind of information did not presents any kind of economical interest but is very valuable to understand the evolution of western Colombia.

So, I want to know if may be some of you heard about this data or may be you know where can I try to request this data.

Best wishes
