Those who have difficulty accepting reports of collagen (a type of protein) preserved in supposedly 80-million-year-old dinosaur bones will scratch their heads with new vigor over a recent report. Supposedly 247-million-year-old fossils from Poland show signs of excellent preservation and even hold blood vessels.To read the rest, click on "Organic Residue Is 247 Million Years Old?"

A team of Polish scientists, publishing in the online journal PLOS ONE, removed the bone's biominerals before using several spectroscopic techniques to analyze the organic remains. They found the same amino acids that modern reptiles use to build proteins like collagen. The study authors concluded, "We interpret the data presented here as evidence for the presence of organic residues in these specimens that may derive from collagen or its degradation products."
But proteins have shelf lives shorter than one million years. This makes discovering them in fossils of supposed great antiquity virtually inexplicable.
