Fossils

or read about people's discoveries, like skim through a fossil eticite book.

Plants are okay, but in my opinion, there aren't enough differences between Annularia and Calamites.

That is because they are the same thing. They are obsolete taxa. Annularia is just the leaves, and calamites is the bark.

They're CONFUSING, it took me forever (duh) to figure that out.

it was ez because leafs and bark r different

Do we need to know the six basic body types of dinosaurs (sauropods, theropods, ornithopods, stegosaurs, armored, and horned)? It wasn't in the list, but I think it might be something to know. Also, does anyone know the bone differences between carnivores, omnivores, and herbivores? At Regionals, we were handed a random sample(not a tooth- that would be easy) of bone and were asked to identify it's diet among the 3 types.

Are you serious?!? Handed a bit of BONE and asked to identify the diet? Did you all ever get a test key? I'd like to know the answer and the test-writer's rationale behind the question. (I mean, I'm sure it's a great question and make a lot of sense, but sheesh...)

That is a bit mean of the test writer. A tooth would be easy to ID the diet, but anything else is just hard.

well,theres always foot claws...

True, but can you really ID the genus with just a claw? You can narrow it down to say deinonychus or velociraptor if it's a sickly-shaped claw at best. (If you're a paleontologist you can, but that's if you're a professional)

[GGuy5]

On those type of Q's they will ask for family or class of the specimen

I can't figure out how to tell the difference between the Mollusk genuses Exogyra and Gryphaea. Can somebody help me out? (Oh, and is it geni...I don't know)

i'm pretty sure it's genera

yeah, its genera...ok...





the top is exogyra and the bottom is gryphaea

see how exogyra kinda curves sideways...it curves out? and gryphaea curves in?...i think thats the difference...(its the difference that i always think of)

[croman74]

I just wanted to compliment packer backer on the nice test he made. It's a lot better than mine.

[GGuy5]

Gryphaea looks like horn and exogyra has a fingerprint looking bottom
