Does anyone recommend any websites for all of the BRACHIOPODS fossils? Especially, Juresania and Leptaena.

It varies on what information that you are looking for. I checked my search history and I apparently used this websites wiki, and also this website
http://www.spaceman.ca/fossil/index.php ... rachiopods. I believe that I also went on Wikipedia too. Hand pick out websites you believe are the best, and if you can't find information, then try to resort to a field guide. For Leptaena, it was SO hard to find information, so I had to generalize half the info on it. Somehow, I still managed to fill the entire page.
For all brachiopods, just explore around. MaYbe use Fossilworks (i'm not big of a fan of it), but don't be reliant on it for the entire binder. Literally half our binder is Fossilworks and copy and paste. We were rushing to finish ~50 specimens in a week. Some of our information could be cut down more.

Don't be too reliant on me answering your questions as well. It's better to grow into an independent person for this event especially. I know most to all of my facts, and just need to add the new info on evolution and cladistics as well as some info from the ornithology binder to make our binder superior than the OC schools.

Hopefully this helps!

Do you guys know the difference between Exogyra and Gryphaea?

It's actually really easy for me to tell the difference between the two specimens now.
Exogyra has a tightly coiled curvy part at the top, while Gryphaea does not.
Gryphaea (when flipped so that you can see the inside), the coiled part is curving toward the empty space and Exogyra does not, and just curls to the top part, and not the back.

I think this was a mistake on our test but i'm not sure
the answer key doesn't make sense in terms of my memory

Specimen A is an Astraeospongia
Specimen B is a Hydnoceras

8) Which of the following correctly classifies Specimen A?
a) asconoid
b) syconoid
c) Calcarea
d)hexactinellida
e) Demospongiae

9) Which of the following correctly classifies Specimen b?
a) asconoid
b) syconoid
c) Calcarea
d)hexactinellida
e) Demospongiae

AK says that 8) is d, 9) is c
but i thought that hydnoceras was a glass sponge, so why is it calcarea if this wasn't a mistake
what is a hexactinellid? I think it's some form of taxonomic rank (hexactinellida)

I agree with you in thinking that the key was wrong. I wouldn't worry about it. Hydnoceras is a glass sponge indeed.

Did you guys find any information about Genus Astarte?

Yes haha
It was so hard to find information online, so I actually had to resort to my Smithsonian Field guide for this one.
Same with Nucula, except I used another field guide for it. It had more information than I could even find on the web not gonna lie

But here's the catch.
If you can't find info, then the test-writers can't find info. (Even if they wanted too)
So many websites conflicted information(all different time periods when the bivalve lived), so I HAD to resort to the field guides

Can we annotate our notes?

Of course!
You're always allowed to. These are your notes anyways. If you don't have room (like I do), create another page of notes just for the information on a specimen. Our proctors never said anything about our annotated lagerstatten page anyways, so I assume that it would be fine. (but we don't use our Lagerstatten page anyways bc I memorized it all)
