Pyramidulina is a member of the Nodosariidae family of forams. They typically have a calcareous-hyaline test (made of calcium carbonate) that is characteristically uniserial (chambers arranged in a line with aperture at one end). n.b. This an exceptionally large species. \u003c\/p\u003e\n\u003cp\u003e- From the Serravalian Stage of the Miocene Epoch which covers the time period approximately 13.82 to 11.63 million years BP.\u003c\/p\u003e\n\u003cp\u003e- Collected from Quammieh Bay, Malta (with permission).\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003eCorrect Labelling\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e- The label on the left of the slide records the genus and species of the specimen as well as the original author and date first described.

Because most foraminifera range from 0.1 mm to 1 mm in size, they do require magnification but are large enough to be seen in three dimensions. Higher powered compound microscopes are only used when preparing thin sections of foraminifera or studying very small species using transmitted light.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Slide\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e- In order to make these slides available at a reasonable price I've had to develop my own. They're hand made from several layers of acid free mountboard and card with a glass cover slip inserted from the side to cover the specimen. Cover slips are very fragile but easily and cheaply replaced if you do happen to break them. The cover slip can be moved sideways (with care, I use another cover slip) if you want to move the specimen or if it has become detached from the background. To reattach just wet the specimen with a very fine paint brush. The background of the slide is coated with gum tragacanth which is used to keep the specimen in place.\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSize:-\u003c\/strong\u003e 3.00 inches long approx.\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003ePostage \/ Shipping Costs:-\u003c\/strong\u003e For multiple orders please request an invoice.
