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. |
