Fossils B/C

[UTF-8 U+6211 U+662F]

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!

Phylum
Class
Genus
Mode of Preservation
This mode of preservation is equivalent to what in Mineralogy?
With this type of mode of preservation can you see the fossils without something (nature, humans) altering it?
Why is this genus shaped the way it is
Time Range
Describe the hinge line
Where do/did these organisms live?

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

Oh sorry. Is there a way to upload images from you computer to the forum?

Not too sure about this (Click to Show Hidden Text)

Mollusca, Bivalvia, Pholadomya
Mold and Cast
???
No?
???
Triassic-Recent
Missing teeth
shallow seas buried in sediment (now deep waters)

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

Oh okay.

Identify specimens A and B up to all major taxonomic ranks. Name why A probably did not live in the Arctic, and name the two different types of hairs of A. Name A's extant relatives. For B, name their diet. Explain why A and B had tusks. Name their diets and time periods. (Click to Show Hidden Text)

Ooh this is a tough one (Click to Show Hidden Text)

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
