Fossils B/C

[azuritemalachite]

Sorry to bother everybody again, but I have another question. Would the Audubon Field Guide to North American Fossils be a useful resource to help study for this event?

I personally like the Audubon field guides a lot, but it's not really recommended by officials. Though any detailed field guide would help a lot.

Thank you! I'm kinda new to this, although I have done Rocks and Minerals. Fossils seems way more intense.

It is at times if the test maker is good and there are real samples. My first invite was pretty intense and I was feeling terrible (because of the flu, you know ). We had to identify which dinosaur bone went to which which is like crazy because I hate anatomy (it's cool 'cause we need it, but I hate studying it. Isn't really my forte) and almost every station had a real sample to look at which is really cool.

I wish my regionals had that, it'll probably just have pictures

My invitationals in R&M last year had really good samples, and then, in regionals, there were the worst quality pictures ever. The ink was all screwed up and pictures were blurry. Ironically, I got 6th place in it.

Haha at my Invite I said, "Everyone did terrible, only some did better than the others." because that's what happened at most events.

Hi Guys
So I'm doing research, and I can't seem to find a definitive answer for the geologic time zone of the Chromista.
Has anybody found anything for that?

HI! So I did a little digging about and I found that Chromista are basically diatoms and diatoms are still alive today with the whole living fossil thing. I might be wrong because I haven't gone very indepth.

Okay thanks
Do you know the time period in which they originated?

Hey, so I've been really confused. Does anybody have any tips on how to tell genus Gryphaea and genus Exogyra apart?
I've seen some that are very distinct, and I can tell which it is. But other times, the fossil looks like it could be either, and I'm having a really hard time differentiating the two.

Notice how Gryphaea always curls under into the shell part and Exogyra always curls over itself. Gryphaea looks like a slug and Exogyra almost looks like an elephant's tusk.
