Extract subtrees from a time slice

[Caetanods]

Most of the studies are focused in a particular clade that corresponds to a taxonomic group and share recognizable characteristics (traits). Examples are families, genera and etc. However, would be interesting to be able to extract subtrees from a time slice of the Tree of Life dated phylogeny. The user could give a set of time slices (e.g., millions of years in the past) and a group (e.g., Angiosperms, Vertebrates, Mammalia) and the output would be all subtrees within that group from the date given to the present pruned by that time slice. With this tool researchers could elect phylogenetic groups that share the same evolutionary time (a time-wise phylogenetic unit), investigate evolutionary trends common to several groups and etc.

This would be awesome. The biggest challenge is that time information is scarce. We might need to figure out a way to bring in more time information from other sources before we are able to make much progress.
