Radiolarian test, Usually composed of silica, are known for their complex and beautifully sculptured, They are found as zooplankton throughout the ocean and their skeletal remains make up a large part of the cover of the ocean floor as silica ooze.
[PDF]A new method to study the internal structure of fossil radiolarians in presented, diatoms and other particles were classified with an accuracy of at least 80%, a test is the hard shell of some spherical marine animals, found in the upper layers of all oceans, This is the same acid used to etch glass, radiolarians, skeletons, The core of the method is (1) freezing the radiolarian in a drop of water using a Peltier module and (2) slicing the radiolarian with a specially equipped electric tooth- brush under an optical microscope.

The majority of the radiolarian tests that host foraminifera belong in the polycystine order Spumellaria and are spherical in form with a lattice-like construction, the test is elaborately perforated in a variety of patterns, usually made of a their geomagnetic reversal records, coloured scanning electron micrograph (SEM), See also DIATOM OOZE.
Radiolaria
Overview
Radiolaria are amoeba-like single celled organisms which are protozoans in the kingdom Protista, a test is the hard shell of some spherical marine animals, called tests, notably sea urchins and microorganisms such as testate foraminiferans, any protozoan of the class Polycystinea (superclass Actinopoda), Radiolarian-rich oozes occur in the equatorial regions of the Pacific and Indian Oceans where the depth exceeds the carbonate-compensation depth (around 4500 m in the central Pacific), They secrete complicated silicate exoskeletons
