Presented is a random sampling of photos of petrified bones
discovered by Ed Conrad in Pennsylvania’s anthracite region.
All are embedded in slate (or shale), which means they had existed
before the hardening of the slushy material in which they are embedded.
Perhaps the most golden rule of geology is that coal is of Carboniferous age, having solidified
a minimum of 280 million years ago. Established science also has long contended that
anthracite is the oldest of the coals, a minimum of 300 million years old.
Whatever animal bones are shown here petrified in anthracite, rest assured that it lived and breathed before this slab of rock was formed.
