the carboniferous period can be sometimes divided into the pennsylvanian and mississippian periods. so you'll sometimes see carboniferous and sometimes pennsylvanian/mississippian.

as for land animals, im not really sure, but since silurian and devonian are right next to each other, you can assume that they're sometime around those periods.

The first tetrapods, which were the first land vertebrates, appeared in the Late Devonian Period. The first animals of any kind to emerge on land where myriapods, a group containing things such as centipedes and millipedes. They first emerged and walked on land in the Silurian. Then there are the reptiles, which were the first land vertebrates that did not need to return to water to complete their life cycle, and they first emerged in the Carboniferous, or, more specifically, the Mississippian.

annularia and calamites are the same plant. annularia are the leaves and calamites is the bark...i dont know why they have different names...youd think they could just call the whole plant the same name, right ;)

wow, that explains a lot of the trouble i was having with those selections!

Carboniferous is the name of both of those combined. It is broken down into the pennsylvanian and mississipian periods.

It was ridiculous. And I mean literally ridiculous, like absurd.
It was 10 stations at 6 minutes each with a lot of questions and a ton of samples, and there were classification questions that werent even on the list, like different groups of echinoderms (one was like holothoidea or something like that).
To show how hard it was, I actually left about 3 or 4 of the stations half done, and i still got 5th. It did manage to crush my spirit though.

This was C division by the way, I heard that B was on the ridiculously easy side of the spectrum.

Division B was crazy easy!!!! You didn't have to write a single word!! It was all multiple choice and most of it was just identification.
