Mystery has long surrounded giant fossils known as protoaxites that resemble tree trunks but are from before trees existed.
For over one hundred years controversy has surrounded these peculiar prehistoric enigmas, exactly what were these tree-like formations of the ancient world and how did they form ?
The giant fossil Prototaxites is a big 400-million year old mystery. The fossils resemble tree trunks, and yet they are from a time before trees existed.
