Carbon-14 dating works for fossils up to about 75,000 years old;fossils older than that contain too little 14C to be detected. Mostdinosaurs went extinct 65.5 million years ago. (a) Can 14C be usedto date dinosaur bones? Explain. (b) Radioactive uranium-235 hasa half-life of 704 million years. If it was incorporated into dinosaurbones, could it be used to date the dinosaur fossils? Explain
A number of scientists believe that the Permian extinction was caused by huge volcanic lava flows (from the Siberian traps) that may have caused low oxygen concentrations compared to the high oxygen levels in the Permian. Does this low oxygen level after the Permian extinction make it likely that dinosaurs, especially large ones, did not evolve immediately after the Permian extinction (252 million years ago)? Why or why not?
Scientists know that the last common ancestor between chimpanzees and humans lived 5-7 million years ago because: O It lived shortly after the disappearance of the dinosaurs at 10 million years ago. O The carliest hominins were found in woodlands The time the last common ancestor existed can be calculated by comparing chimpanzee and human DNA and using a "molecular clock" O Chimpanze fossils first appear in the fossil record 10 million years ago
