C14 in fossil fuels is not the only evidence of a young earth.
Another evidence is soft tissue remains in dinosaur fossils.
A 70-million-year-old Tyrannosaurus rex fossil has yielded soft tissue, including blood vessels and perhaps even whole cells, U.S. researchers reported on Thursday.
“Tissue fragments from a Tyrannosaurus rex femur are shown at left, when it is flexible and resilient and when stretched (arrow) returns to its original shape. The middle photo shows the bone after it is air dried. The photo at right shows regions of bone showing fibrous character, not normally seen in fossil bone.”
Does it even make sense for something 70-million years old to have soft tissue remains? I have things in my kitchen that have hardened solid just after a few years.
