What is it? What did it come from?
Where is a good fossil site for this organism?
Why are there so many of these organism in said fossil site?

Answer (Click to Show Hidden Text)

The foot of a smilodon
Good fossil site: La Brea Tar Pits
So many because Tar pits offered excellent preservation, often chased prey into tar pits.

EDIT: Animals that came to drink at the pit fell in, and are preserved because of the oil in the pits.

I think the last answer would be because a larger animal (say Mammuthus) would be trapped and die, and many would come to feed on it but die in the tar. But the rest is correct, i believe.

Suture Pattern?
Phylum, class, and order of organisms with this suture pattern?

EDIT: yea quizbowl, your answer makes more sense.

Ammonitic suture pattern
phylum:mollusca 
class: Cephalopoda

The suture pattern and the order is incorrect.
