Hello!Following the clues try to find out the mysterious group of vertebrates:
1. This is the only vertebrate group to have hollow bones.
2 The most massive bone found in this group of vertebrates is the "keel" or the "breast bone".
3. Like one other vertebrate group, this group is warm-blooded and mantains a high body temperature.
4. This group lay eggs.
5. It is theorized that this group of vertebrates were the descendants of dinosaurs.
6. These vertebrates are adapted to a highly specialized method of movement of locomotion.
