T. rex "tissue" may just be bacterial scum

When palaeontologists reported that they had recovered soft tissue from a 65-million-year-old Tyrannosaurus rex fossil, the excitement was palpable.

Without going all Jurassic Park, the discovery seemed to open the door to studying biomolecules from dinosaurs and other long-extinct creatures.

It seems, however, that no one will be cooking up a new zoo exhibit from this one. The "tissue" appears to have been layers of biofilms laid down by bacteria and not the skin and flesh of the ancient beastie
