Monkey Puzzle Tree

I love to watch some of the science and nature shows on Public Broadcasting, and some of them I have recorded, so I'm catching up on them now.  Last night I watched a show about how a farmer in Patagonia in Argentina found a dinosaur bone which led to a 2 year project for the paleontologists there. Among the many things I learned is that this type of tree covered vast forests those many millions of years ago and these huge dinosaurs grazed on these, among other things, as part of their very heavy duty veggie diet.  This tree is my brother in law's favorite tree and where ever he has lived, he has planted one in his yard.  This particular tree lives across the street from me, but it is on the endangered list here as the people who live in this house now aren't fans of this living fossil tree and it's prickly ways and the previous owners planted a group of trees very closely together and they are all getting smushed and entangled together, so something has to go.
Araucaria araucana
Monkey Puzzle Tree or more properly araucaria araucana is an evergreen tree growing to 1-1.5 m in diameter and 30–40 m in height. It is native to central and southern Chile and western Argentina. Araucaria araucana is the hardiest species in the conifer genus Araucaria. Because of the longevity of this species, it is described as a living fossil. It is also the national tree of Chile. Its conservation status was changed to Endangered by the IUCN in 2013 due to the dwindling population.
