Schuchertella 4 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 10 49 (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.
