Carnivorous Gastropods of the Pittsburg Bluff Formation
OregonFossil posted a topic in General Fossil Discussion
I found these shells extracted from the matrix. While I've not ID them all yet there is at least one or more of the family Bruclarkia. In Geological Survey Professional paper 922 -Oligocene Marine Mollusks from the Pittsburg Bluff Formation in Oregon, the following is stated: "Bruclarkia, Perse, and Molopophorus, which lack the round aperture usually possessed by herbivorous snails, have long siphonal canals, indicating that they may have been detritus feeders or carnivores, preying upon clams; their familial assignments". Bruclarkia family is now extinct. The top left Gastropod is a Bruclarkia (90% sure) and measures 26.87mm (for reference). My guess is that it is Bruclarkia columbiana. Here is location information on this species: I will get all of these cleaned up and post some complete views so any of you Gastropod fans can ID them if I can't. I was quite excited to find of these fossils within a square foot.-
