Dinosaur Soft Tissue is Original Biological Material Soft tissue cannot remain non-permineralized for millions of years. The best explanation is in my view that the fossils are younger than thought for a long time.
The researchers were even able to chemically tease the fibres apart for further examination, and concluded that the structure of the fossil worm tube casing is “consistent with the ß chitin tubes of siboglinid animals”.3 In other words, the same as seabed dwelling worms such as beard worms today (see photo above).Minerals have not replicated any part of the soft tissue and the carbonaceous material of the wall is primary, preserving the original layering of the wall, its texture, and fabrics.”3And:“The tube of S.cambriensis was flexible, as shown by its soft deformation and preservation, and composed of fibers perfect in habit and parallel arranged in sheets, and then sheets in layers.”Within days they were covered by sediment, perhaps stirred up by a storm—Professor Małgorzata Moczydłowska Accompanying electron microscope photographs showed these ‘perfect in habit’ fibres to be less than half a thousandth of a millimetre wide.cambriensis was flexible, as shown by its soft deformation and preservation—Moczydłowska et al., Journal of Paleontology, 2014They found that the tube casings of the seabed worm Sabellidites cambriensis were still soft and flexible.After comprehensive laboratory analysis, the researchers assessed the seabed worm’s remains to be still composed of the original organic compounds.
We report a systematic investigation of amino acid composition and collagen peptide mass fingerprints (PMF), for a range of samples dating back approximately 1.5 million years.
