Er, I know about them, but the information isn't something you can fit into a single post. You need to do that sort of research on your own to do well in this event. I mean mode of life varies for every fossil, and there is a lot to know about each of those topics.

You can check out the fossil wiki, it has some of the stuff in there.

Thanks, but in specific does anyone have any good websites where I can get information on modes of preservation (filter feeders etc.)? Because I can't really find anything and all the information is mixed data. Also, I was confused about the fossils bearing sedimentary rocks portion. Does that mean we need to know all the fossils that contain sedimentary rocks or the kinds of rocks that may be in fossils? Also, for Index fossils, do we need to know all the Index fossils or just what an Index fossils is? Thanks for the help!

A lingula is different from the other brachiopods because of the way it opens. Instead of going up & down when it opens, the lingula slides open from side to side. but u can always make sure.

I think you have confused modes of preservation with mode of life. Modes of preservation includes petrification and encased in amber whereas mode of life is filter feeders and if it was sessile etc.

For the sedimentary rocks portion, they just asked to identify the different types of rocks.

This is good for us ex-rocks people. We can use (part) of our skills here.

How well do we need to know specific types of rocks... (I figure it's gonna be mostly sedimentary since we're dealing with fossils_
Am I going to need to know intimate details about different types of shale for the state competition?
How does the state competition differ from the regional competition?

So the regionals are definitely different from the invitationals?

For invitationals, I remember we had about 10 multiple choice, 10 matching of detailed descriptions of the geologic time scale, and 15 identifying but I was expecting purely identifying and answering questions about anatomy, habitat, and time range at the stations :/

Probably not...that's more of a question for the Rocks and Minerals event (which isn't around this year)
It's usually harder, but not always. It should be, if your proctor is good, but you never know.

From my experience, it would be way harder than that. However, I was doing Rocks and Minerals and a real geologist was doing the test. When she wrote the test, it was super hard. (55% took the gold) For all we know, the person doing the Fossils test could know absolutly nothing about paleontology and give us an easy test. Either way, it probably won't be that easy though.

My invitationals test was pretty challenging but my regionals test was pretty easy: It was all multiple choice! This leaves me wondering about states but i don't think i'm gonna do it for states neway
