How old was Shaak Ti at the time of her death?

I do not remember where I saw the information, but I remember reading that Shaak Ti was 42 when the Jedi Order fell in 19 BBY (Before the Battle of Yavin). She was born in 61 BBY. However, I'm not sure when she died, as she has died on like three separate occasions, all of them non-canon. In the Mandalorian, the crew working on Ahsoka's design has confirmed that the short montrals and lekku were simply a matter of needing to allow for stunts. Technically, yes, they should be much larger, since Ahsoka was born in 36 BBY, and Season 2 of the Mandalorian takes place around 9 ABY, making Ahsoka 45 in the events of Chapter 13. So since Ahsoka is about the same age that we observe Shaak in the Clone Wars and the movies, her montrals and lekku should be about the same size.
