Like people high on weed, they just passively migrated through floating. Soft parts of the organism are often protected by complex skeletons. They are super duper small; 30 microns to 2 millimeters.

A dude named, Hackle came up with the first classification for these known as Hackel&#8217;s Plates.<\/p>\n<p><a href=\"http:\/\/plato.acadiau.ca\/courses\/geol\/cameron\/Geol3213-Micropaleontology\/Pictures\/Radiolaria\/\" target=\"_blank\" rel=\"noopener noreferrer\">images\/diagrams<\/a><\/p>\n<div id=\"print_remove\"><center><iframe width=\"100%\" height=\"500\"src=\"\/\/www.youtube-nocookie.com\/embed\/bs_XfZ9uaw8?rel=0\" frameborder=\"0\" allowfullscreen><\/iframe><\/center><\/div>\n<h2>Order <font color=\"#0066ff\">ARCHEOSPICULARIA<\/font><\/h2>\n<p><b>Hard parts:<\/b> spicules&#8230; also read notes<br \/>\n<b>Composition:<\/b> ?<br \/>\n<b>Morphology:<\/b> <br \/>\n<b>Symmetry:<\/b> Spherical but it becomes radial through evolution<br \/>\n<b>Habitat:<\/b> ?<br \/>\n<b>Stratigraphic range:<\/b> Middle Cambrian &#8211; Silurian ?
