Fossils

[gneissisnice]

from the needle-like question, i woulda guess sponge, cause they were probably referring to spicules, and Porifera means (pore-bearer), which means that sponges have lots of pores.

Random question ok at one of the stations we had to id the phyllum of a random genus not on the list, it was either bryzoa or proifora. We wern't sure so we read the questions,
they were: name the needle like things that hold up this animal,
why is this considered a "lower animal",
how does this animal control water?,
and why whould the phyllum name make explain these animal
we guessed sponge.. what you you have guessed?

How can SO accept a test with subject matter from *off* the Official Fossils list?!?

Wait a minute...porifera(sponge) is on the list isn't it?....I'm confused.

Sometimes no one but the event writer has seen the event before it runs. It's not like there is a committee or anything, at least at most tournaments.

see from the questions i was getting sponge too but when i looked at the specimen i saw a bryzoan (at least i thought it was) here kinda what it looked like this

and if you think about it would work too i was confused

I have a question based on a question we got at Regionals. We were handed a same of mammoth hair that was ten-thousand years old. This was the question: Is this specimen a fossil?
A. No, because it is not old enough.
B. Yes, because it is evidence of former life.
We guessed B, because we saw a sample of mammoth hair in the book. I know that wasn't a really good reason, but that was the best we had. What's everyone else's take?

10,000 is usually the dividing line, so at 10,001 it is a fossil and at 9,999 it is not. At exactly 10,000? IDK.

I would've probably said B as it makes more sense.

1. spicules
2. Lower animal because it is the simplest animal and evolved during precambrian (proterozoic and even more specific ediacaran) times. Sponges have no tissues or organs
3. Control water w/ collar cells filter feeding, etc
4. Porifera- pore-bearer

That could be several things. I can't get the depth of that object very well. If it is cup shaped, it could be a wierd astraeospongia. If not, perhaps favosites.

They really could have used a better specimen
