Latest Arizonasaurus Stories
A fossil unearthed in China in the 1970s turns out to have come from the crocodile family tree after it had already split from the bird family tree.
Arizonasaurus was a genus of dinosaur from the Mesozoic Era of the Middle Triassic Period about 240 million years ago. It was first found in the Moenkopi Formation of northern Arizona. In 2002, a nearly complete skeleton was discovered by Sterling Nesbitt. The type species, A. babbitti, was named by Samuel Paul in 1947. One characteristic of Arizonasaurus was that it had a large sail on its back formed by elongated spines of the vertebrae. Photo Copyright and Credit
