It has been requested that I do this question and then let someone else post another (Hello wec01)

For number 4 the answer would be Mollusca, specifically Bivalvia (I probably should've asked something along the lines of "What Class fills a similar niche to this Phylum?") since both bivalves and brachiopods are 2-valved, calcareous, bottom-dwelling, filter-feeding, etc. This question probably could've been expressed better.

Here is another question:


1) Identify
2) What are the white, concavo-convex segments called?
3) What are the separations between them called?
4) What is the white substance filling them?
5) What is the tube in the middle connecting them?

1. Orthoceras
2. Chambers(?)
3. Septa 
4. Calcite
5. Siphuncle

Note: for 2, they are also called camera; either works

3. This animal is considered to be the "missing link" between which two types of animals?
4. Some of these fossilized specimens exhibit pyrite disease. What is pyrite disease, and what is one way to combat this problem?
5. Scientists processed these specimens' bones to look for what?

1. Iguanodon
2. Gideon Mantell, 1825
3. bird-footed bipedal species and duck-billed quadrupeds
4. This is when pyrite gets into the fossil and under humid conditions it oxidizes and expands. This can be prevented by storing fossils in dry conditions.
5. remnants of DNA
