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.
A beautiful image. Thanks for posting and alerting me to the foraminifera.eu blog (which I should have known about).
ReplyDeleteThanks. I posted another one. They are not quite as common as the star sand foram found in the Guam samples.
