The ChallengeThe Challenge• How to make a database (e.g., EGI
research database) designed for the professional paleontologist available to the general public?– Constructed at Amoco Exploration (1964-1998)– Technician-based data entry and manipulation– Very user-unfriendly
• There are many such databases.

Paleontologist User Paleontologist User (Process 1)(Process 1)
• Application development – graphic correlation– StrataPlot (Emil Platon)
• Point-and-click ease of use• Software and starting composite standard available to users
as downloads• Easy data entry – Excel format
– User data– EGI research data (~2400 localities)
• Beta-testing– Calibration tool for Chronos Permian/Triassic boundary test
bed
• Taxonomic revision of EGI database

Database Integration Database Integration (Process 1)(Process 1)
Run integration tests for shared localities in North
America
Matching Keys; e.g. Site = Location
Data retrieval; e.g.: “68-71.3 Ma”, “Early Maastrichtian, or “Late Cretaceous”
Matchsimilar
attributes
Set up uniqueattribute values
e.g.: use consistentenvironment descriptors
• e.g., EGI/Arizona linkage
Register DBs with GEON Grid

• What’s the age?– Age constraints for multidisciplinary modeling
• e.g., basin models, sequence stratigraphy, etc.
• Age retrieval without need for specialist knowledge– e.g., EGI database; age stored as lines of
correlation• Algorithm to convert to relative and/or absolute age• Whole section, sample, sample range

Time Scale Time Scale (Process 2)(Process 2)
• GEON needs tie to widely recognized “standard” time scale– Chronos scale
• System centerpiece• Unveiled at IGC meeting – Aug. 2004
• EGI database– Over 700 localities need to be recalibrated
against new time scale– Development of automatic process

General Public User General Public User (Process 3)(Process 3)
• Shared data retrieval issues with Process 2• Educational outreach
– Leverage several sources, e.g.,• Chronos timescale page• Joint development of stratigraphic definitions and
exercises/tutorials with U. Arizona• Other existing sources; DLESE, USGS, etc.
