The most popular example of soft tissue in the fossil record is collagen that was found in a T. rex femur that was supposedly 65 million years old. Of course, collagen can’t last nearly that long. But that’s not the most amazing example of soft tissue in supposedly old fossils.

Precambrian rocks are considered some of the oldest rocks on earth. Well, scientists uncovered some tube worm fossils in this rock layer. These fossils had proteins that were still flexible! And they were dated at half a billion years!

There’s no way these proteins remained intact and flexible for that long. Soft tissue in fossils confirms a young earth.
