Dear all,
I have these plates which contain SEM images of Foraminifera from the Upper Cretaceous (Turonian) from the Ferron Sandstone Member, Utah, USA.
All the samples recovered from shales from this member, The Ferron Sandstone member belongs to the Mancos Shale formation.
This area range from shelf to deltaic environments. The preservation is poor in some samples but fairly good in others.
I am just struggling in identifying them, so I kindly ask for your help!
Majed:
Your concerns are genuine. A large number of documented forms may not be even tests of Foraminifera and the forms documented in frame three from top are too tiny and may be juvenile tests of Foraminifera. You need to subject your material to short ultrasound treatment and provide sharper pictures.

indeed, you have to clean them better with ultra sounds and then check again!
It is clear that a job of cleaning and using the 3D scanning technique would help a lot. However, looking briefly and apparently the first plates appear to be benthic foraminifera of the genus Textularia; The third plate reminds me of benthic foraminifera of the genus Ammonia and the last plate really needs to be more worked on in the cleaning and for me they are difficult to be identified.
try to clean these samples , using ultra sonic bath &get a new pictures. Best wishes..attached a paper that can be helpful for you , especially plate .2 figs. 2,3,4. good luck.
