Re: Fossils B/C
If anyone is having trouble finding time periods/is worried about accuracy, I recommend just using the smithsonian handbook (which is by far superior to audobon) whenever you can.

Re: Fossils B/C
I think Magnoliopsida can be considered a class for it, but some sources say it is also a Division (it should still work I guess).living_fossil wrote:I'm trying to classify Acer, but some of the (credible) sources I have used contradicted each other. It is especially hard to find it's class. This is what I have:
Kingdom: Plantae
Phylum: Anthophyta
Class:
Order: Sapindales
Family Aceraceae
Genus: Acer
Does anyone know the class and/or notice any inaccuracies in my classification?

Certainly not. Just take a look at the 10,000 post thread in Posting Games.gryphaea1635 wrote:(Is this the 1st triple post in scioly history???)

Re: Fossils B/C
Are you from the AB that took 1st at MIT in fossils? I'm sorry about bombing Yale (Was it really that hard in comparison to MIT? Cause last years Yale test was not good.

Re: Fossils B/C
I think this time it was about the same as the MIT test. I remember one question was like "Which other coral is the most related to this coral?" We identified that coral as septastraea and the choices were favorites, halysites, and heliophyllum. We chose heliophyllum because favosites and halysites are in the same order so they can't both be the most related, but I actually didn't really know that one. Looking back, we probably misidentified the "septastraea" and it was probably hexagonaria. Then it would've made more sense.
Another question was about bothriolepis and it was "which of these was not true about the class Bothriolepis belongs to?" 2 of the choices were
a. Most species were herbivorous
b. Many species had true teeth
I remembered Dunkleosteus and thought that it was b, since Dunkle. didn't have true teeth. But according to wikipedia, placoderms did develop teeth so I probably got that question wrong. Im pretty sure the correct answer is choice a.
Also, it had quite a few questions where we had to put specimens in chronological order. That means a lot of flipping in our binder (for me at least).
It also had teeth. The bane of the MIT test
Overall, the test was pretty good though, the "content" wasn't more in-depth, but it was more "tricky."

Re: Fossils B/C
I hate it when they ask you to place the specimens in order. Its such a pain esp when there are like 10. Pretty sure placoderms were either detritovores or carnivores not herbivores. Although technically placoderms dont have teeth because the "teeth" are just extensions of the jaw. Prob hexagonaria cause septastrea is scleractinia.

Re: Fossils B/C
lolol yeah. And like grypaea1635 said, it wasn't a particularly hard test (good job btw, see you at states ). We thought that we could use Yale to experiment test-taking strategies...don't do that during an actual competition, that was really dumb. Basically I flipped through the binder and my partner wrote things down this time around, except I'm really slow, and my partner was not good at spelling. We were all around very short on time and rushed through all the questions. We also didn't expect to get full points taken off for spelling (or more like I told my partner that spelling wasn't important), so we ended up getting about half our IDs marked wrong for spelling....I think that was the reason. Either that or we're actually really bad.varunscs11 wrote: Are you from the AB that took 1st at MIT in fossils? I'm sorry about bombing Yale (Was it really that hard in comparison to MIT?
