Can someone tell me why and how my shell mashes are crystallized?
I’ve made a post showing these pictures but never actually asked why this is. Every single rock in my yard is filled with these shiny crystal fossils and lines. When i search up she’ll mashes, ive never seen any crystallized like this. I would really appreciate it if someone could tell me why and how they are like this. Thanks!
Found in Central Texas
Im pretty sure these fossils are from the cretaceous period
