[ID: Alicia is wearing a maroon shirt and black leggings standing in front of shelves of plants. She signs as text appear: The world’s oldest known dinosaur is the Nyasasaurus parringtoni, dating back around 240 million years ago. (white box with dinosaur image appears). Based on the fossils, scientists estimate it was between 6.5 to 10 feet (2 to 3 meters) long, including its tail. The creature has one distinguishing characteristic linking it to dinosaurs: a bony crest that runs along its upper arm bone. There’s not enough information to say definitively whether the creature was a true dinosaur or whether it was the closest cousin of the dinosaurs. Very interesting!]
