Endogenous Proteins Found in a 70-Million-Year-Old Giant Marine Lizard

Fossil – just stone? No, a research team in Lund, Sweden, has discovered primary biological matter in a fossil of an extinct varanoid lizard (a mosasaur) that inhabited marine environments during Late Cretaceous times. Using state-of-the-art technology, the scientists have been able to link proteinaceous molecules to bone matrix fibres isolated from a 70-million-year-old fossil; i.e., they have found genuine remains of an extinct animal entombed in stone.With their discovery, the scientists Johan Lindgren, Per Uvdal, Anders Engdahl, and colleagues have demonstrated that remains of type I
