Hey Ruben,
Thanks for getting in touch! So the original article is here: http://www.nature.com/articles/srep20252
I don't know exactly how they drew this, but there's an R package called geoscale that does this temporal calibration of cladograms quite nicely. In terms of building the actual tree, you can use software like TNT and then read the outputs into R, which is pretty difficult at times but a really useful skill.
I hope that helps a bit! :)
