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

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)

yeah, its genera...ok...
the top is exogyra and the bottom is gryphaea

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

Gryphaea looks like horn and exogyra has a fingerprint looking bottom
