Palaeontologists have found what is likely to be the oldest known dinosaur, filling in a yawning evolutionary gap. A study in Biology Letters describes Nyasasaurus parringtoni, a new species from 10-15 million years before the previous earliest dinosaur specimens.
The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old! Cyanobacteria are among the easiest microfossils to recognize.
