Fossils B/C

[GoofyFoofer]

That's a toughie.
I think Septastraea's septa (in the calices) are a little more distinct.
Also, Hexagonaria specimens are sometimes polished.

This is oddly specific for this early in the year, but does anyone know how to distinguish hexagonaria and septastraea?

Try this: http://petrifiedwoodmuseum.org/SOCorals.htm
I know, it doesn't show much.....I still might not be doing Fossils..... I have possible event conflicts

Dang, that totally sucks.
I checked my state's schedule and for a moment, I thought two of my most important events were conflicting.

So I know this has probably been asked before multiple times, but do you guys think a page for each taxon is a good idea?
Like for each genus and such?

[GoofyFoofer]

Yes, definitely.
In the competition, you can just ID a specimen by it's taxa, then flip to the taxa paper to answer the more in-depth questions about the fossil.

Question on the taxonomic ranks and such:
Will we be required to identify any species? According to the rule book, it says "Questions will be chosen from the following topics: ... Species," but the list for the event only has one species listed: "neanderthalensis. So, aside from that, the most specific taxon we'll be asked to identify are genus, correct?

[GoofyFoofer]

I think so. I'm new to this event, but if we have to know the species too, then this event is way too hard, even for you Div. C peeps.

[JT016]

Phew. I was hoping genus was all we needed to know.

[GoofyFoofer]

Yup. If it were species, I wouldn't be on this event.

Does anybody have some tips on what to add besides papers for each taxa
Thanks.

I'm looking at the C rules right now(I'm not sure if they're different from B, so B members, look at your own rules first), but it seems you'll need to know about Index Fossils, Absolute dating, preservation, etc. So I think having pages on each of those, probably in the front or back of your binder to be easily located, would be quite helpful. I was planning on having half a page to a page on different half-lives of isotopes(I'm probably just going to take Table N from the NY State Chemistry Reference Table). If you have the room in your binder, having too much information isn't a bad thing.
