“Archosaurs
The reconstructed genome of the common ancestor will be a valuable tool for investigating the evolution of the “archosaurs,” the group that includes all dinosaurs, pterosaurs, birds, and crocodilians. (Crocodilians are actually more closely related to birds and dinosaurs than they are to other reptiles, i.e., lizards, snakes, and turtles.) Green said the genome reconstruction effort, led by UC Santa Cruz research specialist Benedict Paten, yielded about half of the genome sequence of the common ancestor with an accuracy of about 91 percent, and he expects that to improve as more data on bird and crocodile genomes become available.:
