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

Answer (Click to Show Hidden Text)

1) Mucrospirifer (the best brachiopod)
2) Spiriferida
3) Cambrian to Recent
4) This question is left as an exercise to the reader
(jk uhhh Orthida?)

Yep except, (Click to Show Hidden Text)

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. 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
