Search tips:
1. select base table (specimens, samples, localities, references etc);
2. enter one or more search criteria and specify if exact match is required; the default for text fields is to use partial match (i.e., searching for 'asap' will retrieve 'Asaphus expansus'); for classification and stratigraphy hierarchical query is constructed by default; search is case-insensitive;
3. to display images or a map use the corresponding checkboxes;
4. for details follow the links in the results table.
