Answer: …… Locomotor superiority hypothesis (https://dawndinos.com/background/)
2. The living relatives of Triassic crocodiles include………Nile crocodiles……. and the living relatives of Triassic dinosaurs are ……Tinamous……, both of which we are looking at in our study. (https://dawndinos.com/living-archosaurs/)
3. Which continents do our study species derive from?
Answer: … Europe, North and South America, Africa (https://dawndinos.com/extinct-archosaurs/)
4. Why is the DAWNDINOS research team looking at the anatomical data from the living relatives of Triassic crocodiles and dinosaurs when the study is about extinct animals?
Answer: ……To test how well computer simulations of extinct animals might work. (https://dawndinos.com/musculoskeletal-modelling-and-simulation-of-movement/)
5. Why is “XROMM” (biplanar fluoroscopy) important as a scientific method?
Answer: …… It gives precise measurements of the motions of skeletal joints, without skin movement artefacts. (https://dawndinos.com/experimental-data-collection/)
6. Why do we use both experiments and computer models to study how animals work?
Answer: …Because they are complementary approaches – each gives their own unique insight the other cannot give.
7. Which early Jurassic dinosaur moved around on 4 limbs when it was born but became bipedal (moved on 2 limbs) as it grew up?
Answer: ………Mussaurus patagonicus (https://dawndinos.com/early-jurassic-dinosaur-shifted-from-four-legs-to-two-legs-as-it-grew-up/)
8. What does the DAWNDINOS logo represent?
Answer: It represents the struggle between the dinosaurs and the crocodile-line during the Triassic-Jurassic transition, (with Pangaea in the background). (https://dawndinos.com/background/)
9. What 2 methods do we use to generate digitised bones from fossil animals?
Answer: …. Computed tomography (CT) Scanning and Photogrammetry (https://dawndinos.com/ct-scanning-photogrammetry/)

11. Below are artistic reconstructions of some of the extinct archosaurs we are looking at in the DAWNDINOS study. What are they called?
