Zenmaster6 Posted February 16, 2019 Share Posted February 16, 2019 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. Link to comment Share on other sites More sharing options...
Darktooth Posted February 16, 2019 Share Posted February 16, 2019 Do you know what formation they are from and time period? Also better pics are needed. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
ynot Posted February 16, 2019 Share Posted February 16, 2019 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. 1 Darwin said: " Man sprang from monkeys."

The fossils are very small and not easy to pick up. I'll try to get some better shots tomorrow. Thanks : ) Link to comment Share on other sites More sharing options...
DPS Ammonite Posted February 16, 2019 Share Posted February 16, 2019 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. https://en.m.wikipedia.org/wiki/Turritellidae http://shells.tricity.wsu.edu/ArcherdShellCollection/Gastropoda/Turritellidae.html My goal is to leave no stone or fossil unturned.

I got my microscope and magnifying glass out for this one. Microscope and magnifying glass images. Link to comment Share on other sites More sharing options...
Kane Posted February 16, 2019 Share Posted February 16, 2019 Thanks for the closeups. You didn't mention where these were collected, which may help narrow down an age. Was this found in Washington? ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...
Kane Posted February 16, 2019 Share Posted February 16, 2019 I know very little about your collecting area, but I'm hoping others who do collect there weigh in. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Wrangellian Posted February 16, 2019 Share Posted February 16, 2019 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. Link to comment Share on other sites More sharing options...
