Time Control

The age-window is currently set to: top=0Ma base=800Ma with normal taxa sorting

What does this do?

Our system contains taxa from a wide range of geological time. So, if you are specifically interested in one time period - e.g. the present day, or Paleocene, or Early Cretaceous - then it will be easier if it is clear which taxa are present in that time interval. To do this, you can set an age-window using the tools above. NB We now have a nice graphical selector (background image from TimeScaleCreator), but I have left the other selectors on since they give more precise time selection. Note that if you use the selectors in the box the result is reflected by the graphical sliders.

When an age-window is set

• Taxon names will be coloured dark blue if they occur in the age-window and, coloured olive green if they don't.
• Taxa can also be sorted on tables, with taxa that occur in the age-window appearing first (use checkbox below).
