Why does my seqoia pine cone fossil look different than my seqoia cone from my tree in my backyard? - pine cone garland

Why Pineapple seqoia my two differ from each other? One of them is very old fossils, like the cone and the rest of my tree in the garden? In addition to age, in a different form as well? I'd appreciate any explanation!
