Is this Turritella?

[Zenmaster6]

I'm 90% sure these are turritella I collected. Maybe someone knows the species but I doubt it.
If these are in fact turritella, let me know.

Do you know what formation they are from and time period? Also better pics are needed.

Fossil gastropods are mostly classified by external shape and features. This makes it hard to make a good id from a cross section or print.

It will help if You can find one with the external features intact.

It would also help if You kept Your pictures around 1 meg or larger.  That way We can better see the fine details. You can add more pictures in a reply.

I should invest in a better camera. The fossils are very small and not easy to pick up. I'll try to get some better shots tomorrow. Thanks : )

It is probably not possible to give an ID down to genus (Turritella) on these without more distinctive features being visible. Turritella gets used as a wastebasket genus for snails that sort of look alike and probably belong to other genera in the family Turritellidae. Maybe experts, other than me, can confirm that your snails are in the Turritellidae family.

Okay, okay. I got my microscope and magnifying glass out for this one.

Thanks for the closeups. You didn't mention where these were collected, which may help narrow down an age. Was this found in Washington?

They were collected in Washington State near Tukwila. I believe the formation was Steels Crossing (or at least that's what I read online) (if you know a better way to find the formation please let me know) The local geologic map say TC (tertiary continental sediment) However, based on the dates of every surrounding area, the specific date is around the Oligocene period. Other people have identified one of the shells I found in the same area to possibly be a Pecten Bivalve, which indicates this area is no older than 70 million years, or late cretaceous period.  Assuming they are correct, that caps off the possibility of any older turritella look alikes which were extinct before that time.

I know very little about your collecting area, but I'm hoping others who do collect there weigh in.

I'd still like to see larger pics... a magnifier doesn't do much good if your pics are still only 3x4" on the screen. I still can't help with your IDs more than anyone else already has but even experts will need good, large pics.
