Oh sorry. I was a little confused by what you meant by fossil record. If you mean when it existed its from Cretaceous-Present (what I have, Smithsonian, and Audubon say) although some sources say Eocene to Recent
Um, yes.
Your turn!

That's not going to work: google docs needs logging in and a lot of other stuff.

Correct for the ones you answered!

I was looking for concretion but I guess cast is technically correct although you wouldn't be able to tell unless you cut the concretion open.
They are the paleontology equivalent to geodes.
The genus is shaped this way because of its unusually long siphon


Your turn :mrgreen:

A=Mammuthus 
B=Mammut
Mammuthus probably did not live in the Arctic because Arctic ecosystems have low primary productivities meaning that it would be near impossible for a herbivore of this size to exist (wouldn't be enough food for an herbivore of this size to exist)
guard hair and undercoat?
modern elephants
Mammut was a browser meaning they ate trees, twigs, branches, bushes which is why their cheek teeth have high crowns meant for crushing twigs
A and B probably had tusks for sexual selection and possibly acted as weapons. Could have been used for moving objects or digging
A=grazer B=browser
A= Pliocene-Holocene (Early)
B= Miocene-Pleistocene
