Hello! I am new to these forums, so forgive me if I am doing something wrong.

I was wondering about an issue that I've been experiencing with various information, specifically, geologic time periods. For certain fossils, it seems like every resource that I check (websites, field guides, museums) has a different geologic period listed. Which resource should I use for tests? Thanks!

Try to check which one is most recent.

Supposedly the rules say that field guides are the primary source for time ranges... I think technically the Smithsonian handbook is the official source, so I would use that for time ranges, and then use the Audubon for any fossils not in the Smithsonian book. For any ones not included in the field guide you'll have to try to figure out which sources seem the most reliable... (usually not wikipedia though it may be correct)

What I do is write down all of them along with notes on when they were used, revised, etc. so I can put down different time periods depending on who the event supervisor is (university professor, coach, former competitor, etc.)

I've never found it written out in an official-looking post, but I generally just quote this (from Ohio 2015):

If you are willing to trade tests to others, please post the tests to the Test Exchange so that all may have access to it, not just those who give you a test in return.


How about if we both make our tests public as a 'trade' - I feel like people won't post tests unless given something in return, so hence trading.

If you make the tests public as part of a "trade" then that fits within site policy. We just don't want any advertising for private swaps.

Once again I have questions regarding this event.

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! :)

Guys, this is pretty urgent. Does anyone know how long of a rotation Fossils is on with Rocks and Minerals??? And will fossils be an event next year?

Rocks is back next year, replacing fossils.
(I believe it was a three-year rotation, though now it is two-year.)

Why is this?! For the past 13 years this geology rotation has been a THREE year thing, not TWO. Does anyone have any idea why NSO would change this just this year? Finish the three years for fossils!

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

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 not sure about Septastrea specifically, but I think some Scleractinian corals do have symbiotic relationships with some brown algae.

I agree, Fossils has been my favorite event so far, and it is sad to see that they are cutting its span short.

Correct me if I'm wrong, but Archaeopteryx's hip structure is an intermediate between saurischian and birds.
