I wrote a function called "chainsaw" to do something like
this, it saws off all the branches at a particular time
point, then you just have to drop.tip on branch tips older
than your time period. Would that be helpful?

Hi all,
someone knows a smart coding to cut a tree in order to
retain only taxa present in a given time interval bin?
Thanks in advance for any suggestion

"[W]hen people thought the earth was flat, they were wrong.
When people thought the earth was spherical, they were
wrong. But if you think that thinking the earth is spherical
is just as wrong as thinking the earth is flat, then your
view is wronger than both of them put together."
Isaac Asimov (1989). "The Relativity of Wrong." The
Skeptical Inquirer, 14(1), 35-44. Fall 1989.
