Crinoid

1. holdfast?
2. Permian
3. Greek Word krinon “a lily” and eidos “form"


All correct, but the last one is substrates on the ocean floor. It could also be driftwood.

I assume you mean the first one, not the last one?


Yeah, sorry. :|

Where's the question? Or did you mean you were posting the question later

I meant later. Here it is:

Specimen A:
Image

Specimen B:Image

Specimen C: Image

1. Identify Specimen A, B, C
2. Specimen B is a state fossil. Which state?
3. What is the method of reproduction for specimen B
4. Similarities between specimens A and C
5. Define Cross-Cutting Relationships
6. List three conditions for fossilization environments

1A.Batoidea (Ray teeth) 1B. Lepidodendron 1C. Carchardon Teeth
2. I don't think specimen B is a state fossil. However specimen C is the state fossil of Georgia.
3. By the use of spores.
4. Both specimens were used to mechanically digest food by their respective users. They both belong in the class Chondrichthyes.
5. The layer of rock that cuts another is younger than the rock being cut (sorry for the weird wording).
6. They must be buried relatively quickly, kept away from decay such as oxygen or another animal, and has to have a source of leached mineral water so it can be replaced.


I don't know who's supposed to go now, but here's a few questions:


1. Name at least three taphonomy biases in the fossil record.
2. What is a holotype? Which fossil's holotype was found at Solnhofen, Germany?
3. Identify the animal below. What was speical about this animal's jaw?

FYI, you should wait until the previous person has checked your answers before you post a question.
Answer
1.more hard parts than soft parts, more marine than terrestrial fossils, more widespread fossils than fossils with small ranges
2. single physical example of an organism used when the species was formally described. archaeopteryx
3.mosasauridae, double hinged jaw

Yep! My bad. For question #2 I meant to put down Specimen A which is the state fossil of NY
