More Guam Material

I have been studying some more of the material from the island of Guam. The first picture shows a Baculogysina foraminifera shell be tested it a weak acid (white vinegar). It looks to be a carbonate.

The next picture appears to be an Amphisorus foraminifera.

 The following image of a foraminifera appears to be Calcarina.

The last image is of maybe a fragment of an Amphisorus.

Images have a 2-3 mm field of view.

Thanks to Pam for obtaining the specimens and Herb for getting it to me.

Baculogypsina sphaerulata Foraminifera

Baculogypsina sphaerulata foraminifera found on the island of Guam. Image is magnified 23 times under a microscope which should equate to a 2 mm field of view. I think these creatures are also known as star sand.

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