Fossils B/C

Postby hippo9 » September 3rd, 2018, 7:17 pm

Ok I'm gonna start the fossils question marathon I guess.

1. What fossil is this?
2. What is it's temporal range?

This question smells reused
1. Eurypterida 2. 467-252 mya
P.S. Going forwards, can we hide images?

Yes, you can. Just include it in the hide range and it should do it.

Yes both are correct, and if it's been used before sorry, I didn't know.

Anyways some one else can continue!

Describe a few methods of fossilization, e.g. petrifaction.

Here's a few:
Petrification: Over time minerals seep into, and replace organic matter until a hard rock like fossil is left over
Trace: trace fossils are left in rock as impressions such as tracks or burrows
Preservation: preservation occurs when an organism is engulfed in an oxygen free environment such as ice or amber and results in the most intact fossils.

Yep! (Although there's quite a few more that I can think of. I'll post them when I get a chance.)

Edit:
Permineralization (which includes silicification and pyritization), replacement, casts, molds, other trace fossils (also called ichnofossils) such as coprolites, and actual remains preserved by desiccation, polymerization in amber, and tar pits.
I'll be glad if anyone can think of any more!

By that I was just referencing this post.

Ohh yeah completely forgot about that general chat thread.

Anyways,

1. List the following strata in order from oldest to youngest.
2. How can relative dating be used to help date fossils?

2. How can relative dating be used to help date fossils?
1. C, B, A, D, E (And then erosion of A and formation of the dirt layer? Not too sure how A became flat on the top and how D became exposed on the surface. Should probably know this stuff if I'm doing GeoMapping.)
2. Relative dating can be used to determine if two fossils are of around the same age, or if one is older and which. This can be especially helpful in conjunction with the use of index fossils and radioactive dating methods.

1. C, B, A, D, E
2. Relative dating allows geologists to determine the order in which fossils formed. So you can determine a range of dates during which the fossil formed? (idk about this, I haven't studied that much for Fossils yet lol)
