Peneroplis plantus Foraminifera

This looks like a Peneroplis plantus foraminifera. It was found at Pago Beach on the island of Guam. Image is magnified 40 times under a microscope which should equate to a 1 mm field of view.

Thanks to Pam for obtaining the specimen and Herb for the processed material.

Update: I found another one and here is its picture.
