idk I really don't know
Hi other Nessie! (giggles) I'm so sorry that some PEOPLE can't help you! lilly, please don't say you don't know! It's worthless to the poor girl! And Sabrina, please tell me how it helps to copy & paste the question back into this answering box? Ms. Sue, you normally give great help, but this time you gave her a LINK to a bunch of worthless fiddle-faddle? JUST GIVE HER THE ANSWER PEOPLE! I'm sorry for being harsh I hate being mean like this and you are all great tutors you just let vanessa down on this one. That's all i'm saying.
Sending warm hugs from Arendelle,
the thing is nobody here wants to go through the work to help get her an answer and that is really sad. i will see what i can do:)
At the beginning of the paleozoic era there was a big boom in animal life on planet earth, and in the end there was a mass extinction wiping out 90% of major animals. The first period in the Paleozoic era, the Cambrian period, was the time when most major animals appeared on earth. By the next period, the Ordovacian period, organisms could now live on land and now just water. During the Silurian Period, the earth went through a lot of changes, such as glaciers melting. During The Devonian period, The first land living vertabraes, tetrapods, and terrestrial arthropods appeared on the earths surface. During the Carboniferous period, the birds evolved to lay eggs so they could explore further inland. During the permian periond, the largest mass extinction ever recorded happened, wiping out 90% of life.
I did a lot of research on this so I hope it helps! :)
And josd I noticed that you never actually did any research on it, and if you did, you didn't post the answer.
EB: i agree with homo :B

List and briefly outline the six different periods into which the Paleozoic era is divided.
Can someone answer this part for me I am confused and I can't find it anywhere.
Vanessa you're an obnoxious brat, no wonder it was so hard for you to find these answers. Ms. Sue gave them the link to help them look at the right information to see the answers. Yeah people use Jiskha to cheat but it's not suppose to be used for that. And like you said they're great tutors.. TUTORS. Tutors don't give you answer Vanessa they help you find the answers jesus christ.
