Paleozoology
Palaeozoology, also spelled as Paleozoology (Greek: παλαιόν, palaeon "old" and ζῷον, zoon "animal"), is the branch of paleontology, paleobiology, or zoology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
Definitive, macroscopic remains of these metazoans are found in the fossil record from the Ediacaran period of the Neoproterozoic era onwards, although they do not become common until the Late Devonian period in the latter half of the Paleozoic era.
Perhaps the best known macrofossils group is the dinosaurs. Other popularly known animal-derived macrofossils include trilobites, crustaceans, echinoderms, brachiopods, mollusks, bony fishes, sharks, Vertebrate teeth, and shells of numerous invertebrate groups. This is because hard organic parts, such as bones, teeth, and shells resist decay, and are the most commonly preserved and found animal fossils. Exclusively soft-bodied animals—such as jellyfish, flatworms, nematodes, and insects—are consequently rarely fossilized, as these groups do not produce hard organic parts.

Bullseye
by: Aly & AJEverybody's trying to get to me
Every guy is out for the kill
I'm the type of girl worth pursuing
But I won't be caught standing still,no I won't
You're throwin all of your attention on me
Take your best shot I bet you'll miss
You got me interested enough to stand closer
Maybe try a little, kiss
You hit the bullseye, baby
(You hit the bullseye, baby)
Now I'm into you crazy
(You know ya hit the mark)
Don't know how you got me started
(I'm not an easy target, HIT IT!)
You hit the bullseye
You hit my heart
I'm surprised the way you affect me
Like an arrow penetrating my heart
Naturally you seem to just get me
So obviously you're pretty smart
HA HA HA!
I like the way you're all dressed up, messed up
I like the way you don't care
I wasn't certain that you'd ring my bell but
Then you whispered in my ear
You hit the bullseye, baby

Don't know how you got me started

You hit my heart (heart, heart)
You didn't ask me for my number?
Wait, you didn't ask me for my number?

Cause you already got my number, huh
You hit the bullseye, baby
