Fossils B/C

[emd19]

What do they want by insects and crustaceans on the fossil list? I understand what I have to study for every genus, but the terms, insects and crustaceans seem too general, What do they mean by this?

Eh, you just have to be able to distinguish between an insect and everything that's not an insect. I've never actually seen questions asked about crustaceans or insects, I think they only included them so they could give you an insect trapped in amber so they could ask about preservation.

Definitely put in for preservation (amber and trapped in tar, carbonization, too). Naming insects shouldn't be an issue though at my first competition this year I had to identify a beetle that had been trapped in tar. I suppose they could ask the anatomy of insects and evolutionary features (wings) as well.

Obviously there is importance in amber and the distinguishing between a dino and a fly, but apart from that?

In the rules, one of the "possible tasks" they have listed is:
"a. Identify each fossil and record its mode of preservation."

How are you supposed to know how it was preserved? I mean, it's one thing if they give you an insect in amber, but what if you get fossils that are permineralized, petrified, and mineralized? How do you tell those apart just by looking?

Look at the wiki for a basic explanation for this. Those can be very similar, but after a while you can tell them apart. And you would pretty much only use petrification as a term for wood anyways.

why is fossils so difficult and semi frustrating:x

[ThudBucket]

by seeing if their are crystals its crystalisation and only certen fossils can be petrifed .be permization and ect.

Am I the only one who is finding that everybody has their own classification for some of these fossils? I think I've found three different classes, not to mention the different orders, for Juresania. Also, Rhynconellata and Articulata are the same class, right? Just double checking. I believe Rhynconellata is more official.
