While taking tests for fossils I found some inconsistencies in some of the questions and answers, so I'm here to ask you for your experience and information. Thanks!

So I know that birds are descended from Saurischians, so Archaeopteryx is more closely related to Velociraptor than Iguanodon. However, does Archaeopteryx still have the hip structure of Ornithischians?

The anatomy questions come up quite regularly, so I must ask, do any of you have a diagram of brachiopod anatomy that you find very useful (Note: I have a basic understanding of the Articulate Brachiopod and lophophore, pedicle, etc. but am not sure on costae, teeth, growth lines, etc.)

I found on one test that the reason why Septastraea was able to live in the deeper parts of the ocean (while still preferring shallow warm waters) was because it did not depend on a symbiotic relationship with algae, while on another test it said that Septastraea does have a symbiotic relationship with algae. Could anyone clarify?

One last clarification on general anatomy: I want to make sure that I have this down, and please correct me if I'm wrong.
Gastropods feed with a radula, The individuals that make up Bryozoans are called zooids, Brachiopods feed with a lophophore (as well as Bryozoans to my understanding?), the buoyancy mechanism in nautiloids/ammonoids is the siphuncle, and the dividing chambers of coral/the previous listed are septa, as well as the skeleton secreted by polyps is the corallite.

Thank you so much!

I think Archaeopteryx is bird-hipped.
Here you go
Septastrea doesn't have a symbiotic relationship with algae (as far as I'm aware).

I'm really upset about this too. I think it's cause they're trying to make everything a 2 year rotation.

I did not participate in the fossils event in C Division, and will not be doing so this year either, but I'm to assume that it is somewhat similar in format to the Division B test.

Last year the test was comprised of roughly 25 stations where you had 2 minutes at each. There were approximately 5 medium difficulty questions (1-2 short answer + 3-4 multiple choice) at each station. I'm to believe that ~23 stations had real fossil specimens.
