Diamantinasaurus: Beast of the Week

This week we'll be learning about a beast that greatly helps us understand how sauropod dinosaurs ("long-necks") looked and lived.  Check out Diamantinasaurus matildae!Diamantinasaurus lived in what is now Queensland, Australia during the middle Cretaceous period, between 95 and 92 million years ago.  It's considered medium-sized for a sauropod, and would have measured about 52 feet (16m) long from snout to tail. (Yes. 52 feet is only medium for sauropods!) Like all sauropods it would have eaten
