Guidelines: For this paper, do the diversity calculations above for

Spinocyrtia
4
the three general groupings listed. The comparison between

Atrypa
3
brachiopods and pelecypods (clams) is particularly interesting since

Leptaena
2
their similarity in lifestyles and filter-feeding make them competitors.

Productella
2
Do some research on the various invertebrates groups and attempt to

Athyris
1
describe the relations that might have occured between these groups

Orbiculoidea
1
as they functioned in the marine community that existed here.

Spinatrypa
1
Pay attention to reproduction strategies, predator/ prey relations

Mollusca
Bivalvia
Pelecypods (Clams)
Orthonota

(if any), competetive relations, feeding strategies, and even

Nuculites
7
potential mutualistic relations. Given this collection of

Praecardium
6
organisms, what kinds of abiotic conditions would have been

Leiopteria
5
necessary for survival? You should use legitimate on-line

Nuculoidea
5
sources or books in the lab or in the library. I’m asking you

Modiomorpha
4
to take a stab at working in the field of paleoecology even if

Pseudaviculopectin
4
it’s only at an amateur level. I’m not looking for a book on

Grammysioidea
2
the traits of each organism. I’m interested in the relationships

Mytilarca
2
between groups and their general niches in the ecosystem. Many

Palaeoneilo
2
may serve very similar functions in the ecosystem and can be

Actinopteria
1
considered as a single group in your discussion. I suspect that will be

Paracylas
1
the case for the brachiopods and the pelecypods.

* I added some trilobite numbers from earlier trips, since trilobites in general are pretty rare.
