1. Animalia
2. Chordata
3. Amphibia
4. Eryops
5. Lower Permian?
6. Admiral Formation, TX? (If not, the general location is Southwestern US)
7. Drawn-out face
8. It breathed much like normal amphibians (through lungs, mouth, and skin), but could not exactly expand its rib cage because its ribs were too close together, so it had to depress its hyoid apparatus to expand its oral cavity, elevate the floor of its mouth, and close its nostrils to force air into its lungs, and contract the elastic tissue in the lung walls to force the air out.
9. It's spine is stronger, since it had to resist bending due to body weight and provide mobility
10. It had an inertial method of feeding, helping to trap/swallow prey
11. Had three pairs of backward curving fangs
11.5. Carnivore
12. Slow (at least as a swimmer)
13. I think it's false...

1-5 CORRECT
6. Archer County, TEXAS
7. CORRECT
8. Not quite. Unlike other amphibian Eryops only breathed through lungs (could only rely on) because its body to surface area ratio was not optimized for skin breathing.
9. CORRECT
10. CORRECT
11. While this may be true, what i was looking for was that Eryops had projections off its palate that prevented prey from escaping.
11.5 Carnivore/Piscivore
12. Fast swimmer slow terrestrial movement
13. TRUE

6. What is unique about its morphology?
7. What organism did it possibly have a symbiotic relationship with? Describe the relationship.

1. Cnidaria
2. Anthozoa
3. Scleractinia/Stone Corals
4. Septastrea
5. Miocene-Pleistocene
6. Well, the overall shape of the coral is quite random and depends on the energy flow of the environment. In other words if the specimen lived in a high energy environment, it would look different than a specimen that lived in a low energy environment.
7. Hermit Crab. Hermit crab gets a protective "shell" and since coral grows over time, the crab doesn't have to switch shells. The coral gets to move into new areas that may have more nutrients and this allows them to extend their feeding possibilities.

that it had 12 septa per colony (although I'm not sure if that's unique)

For question number 6, I was looking for the organism's variable morphology in different wave environments, but also specifically that high energy environments resulted in encrusting forms, while low energy environments resulted in branching forms (well, sometimes, but they were definitely higher if they were irregularly shaped masses.
