Search Form

Enter a query in the form above to search for pages on this site containing specific words or combinations of words. The text search engine will insert a weighted list of matching documents just above this paragraph.

Each list item (hit) is a link to a page containing matching text, with the best matches shown first. If the page has a title, it will be shown; otherwise only the page's file name is displayed. 

Once on a matching page, use your browser's Find command to drill down on your target.

See below for a brief explanation of the query language, with examples and a few searching tips.

Query Format

The text search engine allows queries to be formed from arbitrary Boolean expressions containing the logical operators AND, OR, and NOT, grouped with parentheses. For example:

paleo or altitude

finds all site documents containing 'paleo' or 'altitude', separately or together

paleo altitude

same as above (spaces and hyphens are treated as ORs)

paleo and altitude

finds all site documents containing both 'paleo' and 'altitude'

paleo not botany

finds all site documents with no 'botany' containing 'paleo'

(altitude not botany) and paleo

finds all site documents containing 'paleo' along with all those without 'botany' containing 'altitude'

paleo*

finds all site documents containing words starting with 'paleo', like 'paleoaltitude', 'paleobotany' and 'paleogeography'

Searching for phrases

Unfortunately, searching for phrases exclusive of component words doesn't seem to be possible with this Microsoft FrontPage Extensions search engine. If you know a workaround, please e-mail me at the address below.

Search Tips

Practice makes perfect with Boolean keyword searches, as with any art form. Keep trying different combinations that are likely to drill down on your target text without being overly broad or narrow. The "AND" operator and the "*" wildcard are your friends.

On Final Approach

Chances are, a search result link won't take you directly to the spot you're after on the target page. If the page index doesn't do the trick, don't hesitate to use your browser's "Find" function to close in on your quarry. See, for example, the "Find (on This Page)" command on Internet Explorer's Edit menu; Ctrl+F is the keyboard shortcut. The find function will save you gobs of time.

Geologic Glossaries and Timescales Online

Need a quick definition? I heartily recommend these online geologic glossaries:

• ^GeoLink Geologic Glossary

• ^Definitions of many useful terms, part of an excellent site on North American geology

• ^US Geological Survey Photo Glossary of Volcano Terms

• ^US Geological Survey Glossary of Paleontologic Terms—oriented toward, well, paleontology

For more technical definitions, see these online compendia of geologic glossaries. 

• ^Glossarist Earth Science Glossaries

• ^Geologic glossaries 

If you're a newcomer to geologic parlance, you might try opening a glossary in a separate browser window for ready access.

Can't remember when the Eocene ended? (I can barely remember yesterday.) Try these online geologic timescales:

• ^University of California (Berkeley) Museum of Paleontology Web Geological Time Machine

• ^US Geological Survey timescale

This site follows the 1999 ^Geological Society of America timeline. For more earth science resources, see the general references cited on the home page.
