A 90-million-year-old fossil of a crow-sized dinosaur named 'Alnashetri cerropoliciensis' has been found in Argentina. The dinosaur weighing in around 0.7 kg is smaller than a chicken and probably hunted small animals like lizards, snakes and mammals. This specimen, given the nickname 'Alna', was a small female that lived in a desert environment and died at the age of four.
