Fossils B/C

[jazzy009]

How common are jellyfish fossils?

Very rare. Most jellyfish are nearly 99% water, it's hard to find that 1% fossilized.

I thought as much. Most likely, most fossils of jellyfish will be cast/mold? Please correct me if I'm wrong.

Your guess is as good as mine (probably better), but I would like to believe if we do get shown a scyphozoa, it'll be a very small imprint in a rock like this:

or this:

There are multiple jellies on that last one.

Has anyone purchased the fossil starter kit?
Is it useful enough to buy, like the fossils mainly show up on tests?
And what is the dinosaur bone piece in the kit of?

I think that we only used it once or twice last year. It's not a necessity.

yeah i agree with blufoster. we have a couple of kits and they just are your most common fossils...nothing you seriosly need...also the bone in the kit is just kinda like a fragment of a bone...

Should I be worried about bones? I'm finishing up invertebrates tonight and I'm starting to get worried about the vertebrates. I can identify whole invert. fossils but things like reptiles have lots of bones...have you ever gotten obscure bones on a test?

[soobsession]

im not sure about you guys...but we had no vertebrates on my test 'cept for osteichthyans....you can check the archived fossils thread...

[blufoster6]

Usually if they give you just one bone it's part of the invertabrae or a tooth. Mostly on vertebrates though they show you the whole skeleton of the organism.

Thanks for the help, guys. I've got another question:
What is the importance of a crinoid column?
