What dinosaurs remain to be discovered?
This week on Frontiers, Peter Evans steps back in time, and talks to the dinosaur hunters who claim we are entering a golden age of dinosaur discovery.
A new study suggests that we have only uncovered a small percentage of the different types of dinosaurs that once roamed the earth, so if this is true, how come we've uncovered so few, and where are they all hiding?
Could digging up new and previously undiscovered species shed light on some of the big unanswered dinosaur questions, not just on how they lived, but also how and why they died?
Peter also talks to one scientist who thinks they may have discovered fossilised remains of blood vessels and even blood cells, within the bones of a Tyrannosaurus Rex. Could the next step be dino DNA? |
