Your turn!

That's not going to work: google docs needs logging in and a lot of other stuff.varunscs11 wrote:https://docs.google.com/file/d/0B9NiZSu ... vYXNz/edit
Phylum, Class, Genus, Mode of Preservation, Why is this genus shaped the way it is, Time Range, Describe the hinge line, Where do/did these organisms live?

varunscs11 wrote:This is better right....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?
Mollusca, Bivalvia, Pholadomya Mold and Cast ??? No? ??? Triassic-Recent Missing teeth shallow seas buried in sediment (now deep waters)
Oh okay.varunscs11 wrote: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

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
