DaisyI said: Shoot! It STILL looks like some sort of Araucaria. Hmmm.... I really wish I was standing under one of my full grown Araucarias in my previous yard. Maybe I could feel some Zen. 
Has it ever produced 15 lbcones? How old is it? Maybe a Bunya - A. bidwillii. I'm leaning towards Bunya.
Many thanks for new pics.
Would love to see a very clear pic of a healthy branch on a white piece of paper with something for scale.
Conifers are hard from pics.
Sorry Daisy still not seeing it like Araucaria.
Not like Araucaria bidwillii..... the trunks of which look like the foot of an elephant.
My last pic is a dead branch on the ground.
