More Soft Tissue Found – This Time in a Mosasaur Fossil

It has almost become commonplace to find soft tissue in fossils that are assumed to be millions of years old. (Read more here, here, here and here.) Recently, a research team at the University of Lund, Sweden, found collagen in a Mosasaur, a marine reptile assumed to have lived in the Late Cretaceous some 100- 65 million years ago.

The research team at Lund used several methods - infrared microspectroscopy, mass spectrometry and amino acid analysis - to ensure that the collagen hailed from the fossil and not for instance from bacteria or some another kind of contamination.

The discovery of soft tissue in a so old fossil challenges the belief in millions of years.

Once again.
